MATLAB does not have width or height functions for normal arrays. You can use size to get the size of an array:
d = size(X)
[m,n,p,~] = size(X)
m = size(X,dim)
You can select the dimension using the optional second argument:
rows = size(X,1)
cols = size(X,2)
pages = size(X,3)

Just for future reference: as of R2020b, I think width and height have been added for arrays: https://it.mathworks.com/help/matlab/ref/width.html?s_tid=srchtitle
