Hello, I would like to write a function that accepts as an argument a variable that could be a series, a matrix or a scalar. The function should behave differently depending on the variable type passed. Is there a good way to do this, i.e. what should the function declaration look like? Thanks, Logan _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
