Examples
1. [y]=wkeep([1 2 3;4 5 6],[2 2]) y= 1 2 2. [y]=wkeep([1 2 3 4 5 6],3,'r') y= 4 5 6 |  |  |
[y]=wkeep(x,l) [y]=wkeep(x,l,opt)
Real, complex or string type input vector or matrix
Length of matrix required
Character input to determine which side to extract from
This is an Octave function [y]=wkeep(x,l) extracts a vector of length l from the centre of input vector x. [y]=wkeep(x,l,opt) extracts vector based on opt which could be 'l','r' or 'c' (left, right or central).
