What kind of multiplication is going on here?

Apparently multiplying by '*' utilizes matrix multiplication, while multiplying by '.*' is element-wise multiplication.

So if I do in the command:

[-5: 0.1: 5]*[5]

I get an output like it's doing scalar multiplication with the 5. But I don't think a 1x101 matrix should be able to matrix multipy with a 1x1... And given that the '*' operator was used, why would there be any output at all?

The degenerate case of a 1x1 matrix IS a scalar and so '*' reverts to scalar operation.

It would be simply too inconvenient if it weren't the case.
