Error in Linear Algebra Matrix Vector multiplication

[jacarvalho]

First, thanks for these resources!

In VIP Refresher: Linear Algebra and Calculus, it says

Matrix-vector multiplication – The product of matrix A \in R^{m×n} and vector x \in R^{n} is a vector of size R^n, such that:

Shouldn't it be instead:

of size R^m, such that:

The same for Matrix-Matrix multiplication.
