Pad - Pad a dataset with traces of zeros or nearest value
Pad n1= n2= n3= extend=0 < in.H > out.H beg[] end[]
[nx] Add nxout-nx-begx to the end of the cube dimension (such that the total dimension along the x axis will be nxout). [0] will pad to the next power of 2
[0] Add begx to the begining of axis x
[0] Add endx to the end of axis x (overrides nxout)
[20] Maximum amount of memory to use
[0] Whether (1) or not (0) to be verbose
[0] Whether to extend with the nearest point (1) or zeros (0)
Pad 3-D data with traces of zeroes or value of nearest point.
