[Gretl-devel] matrix-to-scalar details

Hi, I stumbled over some details of gretl's automatic conversion from 1-element matrices to scalars. See: <hansl> m = {3.3} eval typeof(m)        # 3 (matrix) eval typeof(m[1])   # 1 (scalar) eval typeof(m[1,])    # 1 (scalar) </hansl> I find the last result a bit inconvenient; the "1," specifies an entire row IMHO, and it's just by coincidence that it only has one element. The one-element property also isn't the relevant criterion as can be seen from the first result on the "full" one-element matrix m. The implication is that doing nelem(m[1,]) fails in this case because of a wrong type (scalar). So either it would be good if a row or column-indexing specification returned a matrix type, or alternatively if nelem() worked on a scalar as well (and would then return the value 1). This is with 2020d. thanks sven
