Inner matrix dimension problem

a = ones(1,10);
b= zeros(1,10);

Take the codes above as an example, both of them are having 1*10 matrix. How do I change either one of them into 10*1 matrix?

It is useful if you post, which command is failing.

Answer 1

You can multiply the vectors by

a * b.'
a.' * b
dot(a, b)

Take the example above, what about square of 'a' matrix? I have a error of

Inputs must be a scalar and a square matrix.

@Alex: I cannot follow you. I asked for the failing command. It is much easier to solve a problem than to guess, what the problem is.

What does "Take the example above" mean? Do you mean:

a = ones(1,10);
b = zeros(1,10);

"what about square of 'a' matrix" ??? Do you want me to guess that you used:

a = ones(1,10);
c = a ^ 2

And if this causes an error, I could guess again that you meant:

a .^ 2

for an elementwise squaring. Please mention the details.

@Jan Simon: now my code is

c = a^2;

and the command is failing because of the

 Inputs must be a scalar and a square matrix.

but using

 c = a.^2

can worked.

And maybe it creates the wanted result. It would be useful if you mention, what you want as result. Perhaps a * a.' is wanted.
