1164	vector() can't handle matrix flattening!?	asodja	asodja	"The assigment {{A := diagonal(vector(ones(1, 4)));}} gets expanded to {{A := { {1,0,0,0},{0,1,0,0},{0,0,1,0},{0,0,0,1} } }} and fails, while assignment {{A := diagonal(vector(ones(4)));}} (notice the params passed to {{ones()}}) works fine.


The error produced by the first option (which fails) is:

{{

}}

It seems that the function {{vector()}} can't handle matrix flattening!?
