MATLAB: copy a specific portion of an array

Question

I am trying to copy a few elements from a matrix, but not a whole row, and not a single element.

For example, in the following matrix:

a = 1 2
    3          


        

Answer 1

You are not "removing" the second column, you are referencing the other column.

You should read some of the Matlab docs, they provide some help about the syntax for accessing portions of matrices:
