Hello

(Sorry for my poor english)

For a post-treatement of finit element model, I need a function to get the maximum and minimum for a selection of values.

I have a matrix A (dimensions n*n) that define the differents selections (0 value not to be considered, 1 value to be considered), and a matrix B (dimensions 1*n) with the complete list of value.

I think there is to way to solve my problem.

1* : create a copy of the function multiply which give the maximum instead of the sum ( Cij=max(Aik*Bkj) instead of Cij=sum(Aik*Bkj) )

2* : a function that give the maximum (or minimum) by row or column for a given matrix

I work with VisualStudio Express 2013 under Windows7Pro 64bit. I have installed MathNet using NuGet packages manager.

I’d like to try creating this function using copy of existing functions (multiply or maximum), but I never open the source code of mathnet.numerics before, I even don’t know where to find it.

Best regards
