Dear list,

I'm struggling to use the matrix functions:

1) I have a nx14 matrix called A and would like to extract a new matrix
that consists of line i of Matrix A. 

2) I'm running a loop, and in each stage, I create a new 1x14 matrix. I
would like to append this line to a matrix B.

3) Then I would like to calculate the standard deviation of each column
of matrix B.

Thank you very much for your help!
