MATLAB: Referring to multiple columns

columncolumnsmatricesmatrix

Hi,
mat =
 7    8    9   10
 12   10    8    6
How can I refer to the first two columns of the matrix above? Thanks in advance.

Ahmet - if mat is your matrix, then to get the first two colums (and all rows) you could do
 mat(:,1:2)
which would give you
 7     8
 12    10
Note how the first colon indicates that we want all rows, and the 1:2 means that we want the columns one through two.
