Hi. Let's say that I have a 4x4 matrix and i need to select the terms that are optained by crossing out the first column and the second row. I tried with submatrix function but i could not cross out the second row(my matrix is 4x3 and i want it to be 3x3). How do i do it correctly? I'm completly new to MathCad so be patient with me.
Thank you
Submatrix should work.
Submatrix is useful but you have to distinguish three cases (first, last or middle row/column) which makes it a bit unhandy to program. Using a simple loop might look bold but does the job pretty well.
The attached utility function might come handy
Nice function.
