Re: [Gretl-devel] problems with automatic matrix-to-scalar conversion

As regards built-in functions this shouldn't cause problems, because whenever a matrix argument is wanted, a scalar will do (it being treated as a 1x1 matrix). As your example demonstrates, however, that was not the case for user-defined functions. But that's now fixed in git: if a scalar is passed as an argument to a user-function that wants a matrix, we create a temporary 1x1 matrix to satisfy the demand.
