Hello!
I'm new in mathametica so I'm sorry if this question is too simple ... I've just couldnt find it in index...
Soppose I have a matrix M with l rows and k columns, and I want to cahnge column i (0<i<k) with another column, I need mathematica to be able to update the other values in the matrix according new column using elementary row operation. (I mean like "column i = column i + 3*column j").
For example if I got following matrix:
2 3 4
0 1 1
and I want column 3 to be 0 1 so mathamatica could give me the new matrix wich is :
2 -1 0
0 1 1
Does matheatica have such function ?
Thank you ahead !
