Hi,

trying to find the length of a vector by taking the square root of the scalar product, I get this (in ginsh):

> v = [[a,b]];
[[a,b]]
> r = sqrt(v * transpose(v));
sqrt([[a,b]]*[[a],[b]])
> evalm(r);
matrix::pow(): don't know how to handle exponent

The reason is that the scalar product evaluates to a matrix with a single element, not to a numeric. Is that intended?

Thanks,
