In this case the ' is a shorthand way of calling the ctranspose function. You may also want to look at .' which is shorthand for calling the transpose function.

You can simply try it in the command window:
in = 1:10;
in
in'
I've avoided the name "input", because this is an important Matlab command and overwritng it can lead to unexpected results.
