Calculate Matrix Inverse Without The Minverse Function In Excel

I am creating a data sheet to be completed by other users. I would like to
format the text cells (name, etc) to have text entered as uppercase
automatically although the user might use title or lower case.

UPPER function cannot make cell look at itself and perform the function

Excel 2003

Right now I have a sports league with 8 teams, I'd like to create a random 7-game schedule where each team plays the other team only once. Essentially this will be a 7-game round robin. However, I'd like to be able to use this for any number of teams and games.

I'd like to do this in Excel, but I can't figure out how to have a randomly generating non-repeating macro with text values in cells.

So right now I have a column of 8 values and need matrix of 7 columns by 8 rows next to it.

I've found this thread that has one for numbers, but I can't figure out how to do it for text values...

Thanks all!

So I've got some data, which has the approximate form of a sine function. I want to find all the x-axis intercepts. I tried using the intercept function and swapping around the y values for the x values, but it only returns 1 value (so I'd guess it uses a linear regression to estimate a single line through the axis).

I was thinking of trying a nested if/and statement but I haven't quite figured out how to do it. Basically I want to identify the two values where it switches from positive to negative and also indentify the values where it goes negative to positive, I can then fit a straight line between them to find a better approximation of the intercept (though it might not be necessary). Preferably I'd like it all one function as I'm not doing it in VBA (I might do later though, we'll see).

Can anyone suggest how I'd find these value or the x-intercept. Any help would be greatly appreciated.

Is there a worksheet function that will generate all possible combinations of
a set of given numjbers. For example, 1, 3 and 8 would generate 138, 183,
318, 381, 813, 831 and so on...

I am trying to work out how to calculate the geometric mean of a series of values, some of which are negative, ie. investment returns over a series of years with some negatives.

The Geomean function doesn't work because it only uses positive numbers.

Any help would be greatly appreciated.

Hello, please help me out with this one.

So I am at work workin on this report and I need a function that will make Excel automatically insert the today's date in a cell (let's say D90) when I fill the content of another cell (for example C90) and the that will be inserted will never change. I tried to use the =TODAY( ) function but it keeps updating the date in the cell to the current date if i reopen the worksheet 2 days later. I need the cell to keep in the cell the date of the day when I filled in the content of cell C90 and do not updated it every time i open the document to the actual date.. Thanks in advance!!

Good day... I need an IF Function that will allow me to action a time in a time range:

... If the time 04:16 falls in the time range 04:00 - 04:29, than put a one (1) in the filed x...
... If the time 04:16 doesn't fall in the time range 04:00 - 04:29, than leave the x fiel empty

Any help is appreciated.

I have a spread sheet that prints in duplex no matter what I do. I have made sure the printer duplex function is turned off but yet it insists in printing duplex. It is only this one workbook other workbooks print fine.
I hope you have an ansewer.

Is there any way to automatically lock in the date after you pull it up with the TODAY function? Or is there another function that will do what I'm trying to do?

I want it to automatically fill in today's date, when a certain empty cell has a value put in, then freeze there.

Thanks in advance!

I have a spreadsheet set up with an employees information, including the start date. After each year that the employee is working, he gets bumped up on the pay scale. For this reason, I only need to know how many years the employee has been working, rounded down to the nearest year.

This is what I have so far (hire date is in column B):

=((TODAY()-B4)/365)&" YEARS"

This function gives me a number with many decimal places.

I tried:

=ROUNDDOWN((TODAY()-B4)/365),0)&" YEARS"

It tells me I have too few arguments. Please help!

I need information on how to enter the proper syntax (formula) so that excel
can calculate overtime hours. In california over 8 hrs in one day is
overtime. The 8 would be considered regular hours and anything over is OT.

I have cells in a column, some colored yellow, some not. I am trying to use
the SUMIF function to sum only the cells in the range that are colored. Can
this be done? Can I enter something in the "criteria" part of the formula
that can do this?

=SUMIF(D3:D13,"criteria",D3:D13)

I also tried to use the CELL function's color feature, but I couldn't get it
to work right. I don't know how to get Excel to recognize if a cell is
colored in a formula.
=CELL("color",cell)

It might just be that I don't know what this means in Help:

"color" --> 1 if the cell is formatted in color for negative values;
otherwise returns 0 (zero).

Can anyone help?

I need a formula to calculate Turn Around Time. Find below the sample data and details for your reference.

Received Date & Time: 10/29/2010 3:27:00 PM
Completed Date & Time: 11/1/2010 3:57:32 AM
Business Hours: 08:00 AM to 05:00 PM
Non Business hours: 05:00 PM to 08:00 AM
Weekdays : Monday to Friday
Weekends: Saturday & Sunday

If I calculate TAT for this time period it should show me 1 hour 33 minutes, why because business hours are closing by 5:00 PM on 10/29 so it should not calculate duration after 5:00 PM to until 08:00 AM on next day, however 10/29 is Friday so formula should calculate the duration from 10/29 Friday 3:37 PM to 10/29 5:00 PM and again it should calculate from 8:00 AM on 11/01 Monday and formula should skip Saturday & Sunday.

In this scenario I have completed the task before 8:00 AM on 11/01 so it should show duration of 1hour 33 minutes.

Please let me know if you need any more details

I am using the code below to disable the save function very successafully. However, is there a work around to allow a macro to save?
----------------------------------------------------------------------
Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)

'this disables the save function on the XLS

MsgBox "****Save is Disabled****"
' Following line will prevent all saving
Cancel = True
' Following line will prevent the Save As Dialog box from showing
If SaveAsUI Then SaveAsUI = False
End Sub

I would like to know how to make excel calculate which inventory is left in the FIFO method, quantities that are bought first are the first to be sold. Basically where the quantity and price is derived from.

For example:
APPLE
bought 100 on FEB 1 @$1
bought 500 on FEB 1 @$1
bought 1000 on FEB 10 @$1
sold 300 on FEB 12 @$1.5
bought 100 on FEB 13 @$1.1
sold 100 on FEB 13 @$1.2
bought 1000 on FEB 14 @$1
bought 400 on FEB 15 @$1
sold 2000 on FEB 19 @$1.5

For this, the formula/function would know that:
=>for the 300 sold on FEB 12, 100 bought on FEB 1 is depleted and 200 of the 500 bought on FEB 1 is depleted.
=>for the 100 sold on FEB 13, the 100 bought on FEB 13 is depleted
=>for the 2000 sold on FEB 19, it knows that:
==>the 100 bought on FEB 1, the 200 of the 500 bought on FEB 1, and the 100 bought on FEB 13 is depleted so it can't consider those quantities
==>it would consider the remaining 300 of the 500 bought on FEB 1, 1000 bought on FEB 10, and 700 of the 1000 bought on FEB 14

The remaining quantities that are left would be the remaining 300 of the 1000 bought on Feb 14 and the 400 bought on FEB 15.

I would like to know for each sold transaction, which quantities at which prices on which day were sold.

Thanks in advance!
