The array size need to monitor. It's simple and effective with size(x) but no name or location. It would be nice to print if out this way:
fprintf(' size(xyz) at location 123 is [%d %d %d] \n',size(xyz));
because size(xyz) is "unknown" and how to write [%d %d %d] to print size(xyz) in one row?

>> A = rand(2, 3, 1, 4);
>> fprintf('size(A) is %s\n', mat2str(size(A)))
or
>> A = rand(2, 3, 1, 4);
>> fprintf('size(A) is [%s]\n', int2str(size(A)))
Note that the spacing between the elements of the size may be a little different for those two approaches.

John - is xyz your 3D array? If so, then try
fprintf(' size(xyz) at location 123 is [%d %d %d] \n',size(xyz, 1), size(xyz, 2), size(xyz, 3));

xyz = randi(255,12,13,14);
fprintf('size(xyz) at location 123 is [');
for k=1:ndims(xyz);
fprintf(' %d',size(xyz, k));
end
fprintf(']\n');
or
fprintf('size(xyz) [');
fprintf('%d ',size(xyz)');
fprintf(']\n');
Or do you have a requirement that stats that you can only print this in one line?
