Matrix pointwise operation using a function

Question

How do I change the value of each element in a Matrix that involves a function call. Something like

matrix[i,j] = funct(matrix[i,j]*2)-1;

Answer 1

You can use MapInplace, for example:

matrix.MapInplace(Math.Sin);
matrix.MapInplace(x => Math.Sin(x-2));

Or as in your example

matrix.MapInplace(x => funct(x*2)-1);
