Hi Everybody...

I need rapid help by anyone about inversing of a matrix.

you know inversing

1 2 3
0 5 8
4 7 9

*
inverse

=

1 0 0
0 1 0
0 0 1


i need the inverse matrix... I need the implementation of finding that matrix in c.

I am holding the matrixes in linked list. Coz any matrix can be input from a file... And so there can be any size in result matrices..
I searched the net.. I couldnt fine any useful thing...

Thnx for now...

Did you try to google for how to do it?

I wrote a program a while back in C to compute the inverses of n x n sized matrices. It's available at my website http://grimpirate.t35.com/articles/ansic/ansic.html The source code is in pdf format though. Hope it helps.

If I recall correctly from my maths lessons, you need to find the equivalent matrix of cofactors, transpose that, and divide by the determinant. Enjoy.
