concatentation operator not implemented for `matrix'

[Claire Heaney]

Hi there

I'm using octave 3.6.2 with the symbolic package in Ubuntu 12.10

There is an error, when, after calculating two scalars, a and b

        a=p2(1,1);

        y1=(x-p1(1,1));

        b=subs(y1,x,a);

I then try to store them in a matrix

matrix(row,1:2) = [a,b]

Here p1 and p2 are coordinates, and y1 depends on the symbolic x.

The message is " concatenation operator not implemented for `matrix' by `ex' operations".  Does anyone know whether the problem has been fixed?

Thanks

Claire
