How do I isolate a specific column within a vector

Hi Guys,

How do i isolate a specific column within a vector? Like, how do i extract the 4th column only from a 5x5 matrix? What do i code to specifcally get the 4th column values to be presented as a new vector?

TIA

x = rand(5,5)

x = 5×5

0.0113 0.4122 0.7657 0.0161 0.4709 0.3690 0.4130 0.6656 0.8250 0.0153 0.4433 0.3748 0.1919 0.4600 0.6638 0.7265 0.4383 0.4087 0.0044 0.5566 0.3118 0.2547 0.2757 0.9528 0.7364

y = x(:,4) % extract the 4th column only from a 5x5 matrix

y = 5×1

0.0161 0.8250 0.4600 0.0044 0.9528
