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) = [];
