matrix product different sizes

I have three matrices, A of size 46-by-46 and B of size 36-by-36, C of size 36-by-10. I need to compute A*B*C

How would I do it ? Doing ans=A*B*C, can't work out and hint wrong

Can I use the if sentence to solve this problem?

The multiplication of a 36-by-36 and a 36-by-10 matrix is mathematically defined and creates a 36-by-10 matrix. But you cannot multiply this with a 46-by-46 matrix.

The readers cannot guess, what you want as result of this, so there is no chance to know, if an if statement would be useful.

What do you expect as result?

By the way, please do not explain the error message in other words, but post a complete copy of the original message, when you discuss in the forum.
