[lamouline69]

Hello,

I'm interesting to kown how it's posible to extract for example the firt colum of an array.
I did only program in RPN mode with HP50G and now I try to do the same programs of topography with the prime.

with RPN mode:
I want to extract the first colum, and transform this in a list like this:

array name M1
in RPN :

M1 1 COL- ->ROW ->LIST

I hope you undersdand my question and thanks for your help.

Do you mean like this:

RANDMAT(M1,3,3); // to get a matrix in M1
L0:=mat2list(transpose(M1(-1))); // The first column of M1 transposed to a row, and then converted to a list
