inverse matrices
Have you looked at the MINVERSE function?

inverse matrices
this might be a stupid question but that returns 1 number. do I put that in
the 36X36 to retreive all the numbers? "David Biddulph" wrote: Have you looked at the MINVERSE function? -- David Biddulph "Chey" wrote in message ... does anyone know how to do inverse matrices in excel Mine is 36X36 I want to see the inverse of each number 36X36 Thanks Chey |

I want to see the inverse of each number 36X36 It's an array calculation and you will have to select a suitable size matrix to hold the inverse. I take it that it's not the reciprocal of each element that you want. James Silverton Potomac, Maryland E-mail, with obvious alterations: not.jim.silverton.at.comcast.not |

inverse matrices
I have been looking at the example excel gives and I can not seem to get it
to work They say and what I did is typed in the numbers 4 -1 2 0 Then I put in my aray =minverse(a2:b3) it comes up with 0 so that matches then i select A5:b6 then I pressed f2 but when i do ctrl shift and enter all together it does not do anything. That is where my problem is coming in. thanks chey "James Silverton" wrote: Hello, Chey! You wrote on Tue, 30 Jan 2007 12:42:14 -0800: C "David Biddulph" wrote: ??

With A5:B6 selected, type =MINVERSE(A2:B3) hold down a [Ctrl] key and a [Shift] key and press [Enter]. On my system this fills A5:B6 with a single array formula which returns 0 0.5 -1 2 in each cell, i.e., 0 in A5, 0.5 in B5, -1 in A6 and 2 in B6. |

Chey -
Try this (following most of your example, except where you may have erred). Enter the numbers in A2:B3. Select cells A5:B6, and type =minverse(a2:b3) but don't press Enter. Instead, hold down Control and Shift while you press Enter. - Mike http://www.mikemiddleton.com "Chey" wrote in message ...
