So this is my 4 dimensional matrix and i want to find its transpose using a for loop.

A requirement for a (2d)-matrix to have a transpose is that it is square.
Ok, it's nonsense.

You can use the MATLAB permute function for this and not use any loops

Let me first ask, what is it that you actually want to do. What exactly do you mean by the "transpose" of a 4 dimensional array. Ideally please provide a simple example, of your desired input array and output array.

Maybe this does what you want, which is transpose the first two dimensions:
permute(val,[2 1 3 4])
Or you could use this function to get the same result:
pagetranspose(val)
