I have a matrix A of 522x40 and another matrix B or 522x1 (they contain spectra, where A is the response and B is the wavelength.

I would like to plot on a graph the first 10 columns on my matrix together, is there a command like plot (B, A,:[1])) but for multiple columns ? or do i have to do

hold all plot (B,A,:[1]) plot (B,A,:[2]) etc ?

Many thanks in advance !!!!!!

Did you read the plot help? It explains how to plot columns of a matrix.
