Hi, I'd like to know whether I can rely on a behavior in gretl 2017a which seems to fail in 2016d (and earlier?). The following is intended usage and runs fine here on 2017a: <hansl> function void mscheck(matrix m) print m end function # call with actual matrix mscheck(I(2)) # call with scalar as 1x1 matrix substitute mscheck(3) </hansl> However, it seems that passing a scalar to a matrix argument provokes a type mismatch error in gretl 2016d. (Couldn't run exactly the above example now, but the error was pretty clear.) So, is that a new feature in 2017a and is here to stay, or just luck? thanks, sven
