Access Matrix by row or column

[Stevetuc]

Is there a command to select a specific column or row of a matrix?

Ie in Matlab this works:

A(3, : ) % Extract third row

The colon is used as a wildcard. I cant find a way to do this on the Prime except using SUB(), but that requires you to enter lists containing start and end indices of selected region so is not as convenient as wildcarding.

Actually, for a 2D Matrix, just using A(1) will select the 1st row ,but how to fo this for a column? I tried A(:,1) but this errors.
