1x1 matrix addrow problem

But if I have a 1x1 matrix A=(a1) and I want to add a new element "anew" either before a1 or after a1, so it becomes A=transpose([anew a1]) or A=transpose([a1 anew]) respectively, the ADDROW doesn't work.

I could use "append", but it brings the new element to the end of the vector and the size of the vetror becomes 1x2 (row) not 2x1.

I'm not real sure of your objective, but does this help?

a1:=1;
M0:=[a1]; // Original one element matrix
transpose(prepend(M0,0)); // ==> transpose([0 a1])
transpose(append(M0,0)); //==> transpose([a1 0])
