how do I call just a column of a matrix
in matlab A[ : ,1] how is that done on the prime
In Home and normal programs only (not CAS):
M1(-2) → column 2 of matrix M1
M1(2) → row 2 of matrix M1
If you need a syntax that works in CAS as well, use the col() and row() commands:
col(M1, 2) → column 2 of matrix M1
row(M1, 2) → row 2 of matrix M1

thanks so much, that did it. I spend an hour or two searching the manual and if you don't know the secret code you are pretty much helpless
