## How To Get Second Column Of A Matrix In Matlab

Hallo, I have matrix (793576x3) that consist of x,y,z, which are x = longitude and y = latitude and z = depth.

- The OP wants to fliplr the second column of A and to multiply it with B to get C.
- I'm having a hard time in trying to get rid of linearly dependent columns of a matrix on matlab. I was trying to run this code . for i=2:22 if rank(D(:,1:i))==i-1 D(:,i)=[]; end end for a 30x30 matrix with rank 22, which means that I have to get rid of 8 linearly dependent columns. In this code I am just getting rid of the first ld column and the the following one that is not ld. Does anyone
