Matrix dimensions must agree -- error with Matlab old versions

[mahmoudnafifi]

If you faced the following error in Matlab:

Please replace the lines 55 and 56 in synthWBmodel class and the lines 55 and 56 in synthWBmodel_GPU class with the following lines:
diff_u=abs(repmat(Iu,[1,size(A,2)])-repmat(A,[size(Iu,1),1]));
diff_v=abs(repmat(Iv,[1,size(A,2)])-repmat(A,[size(Iv,1),1]));

The old Matlab versions don't offer this broadcasting operation. In the new versions of Matlab, this repmat operation is automatically applied when the first/second operand is a single row vector and the second/first operand is a single column.
