Inverse of NxN Matrix

[hungvu]

How do I write the code to calculate the inverse of an NxN matrix? Thank you in advance.

I think the best you can do is download chapter 2 of "Numerical Recipes". The complete book is free on-line and the algorithms are available in a number of versions such as C, Fortran... Converting from one of these to VB shouldn't be too difficult. From the home page

you can then, for example, jump to

My favourite method is the LU decomposition and it appears that handheld calculators by HP use that too for matrix operations.

Try searching this forum. I think some VB code and a description of the algorithm was posted.

Possible search keys are: inverse, gauss, matrix.
