How do i extract a column from an array

I need to extract a cloumn from an array using Col1 = A(:,3)

Answer 1

[Voss]

This stores the 3rd column of the array A as Col1 (and displays Col1 in the command window):

Col1 = A(:,3)

Is that what you want to do?

Or by "extract", do you mean to want to store the 3rd column of A in a separate variable and also remove the 3rd column from A?

If so, you can do:

% store the 3rd column of A as Col1

Col1 = A(:,3);

% remove the 3rd column from A

A(:,3) = [];
