This must be a very basic question, but since i've just started diving into linear algebra, it's sort of new to me.
Matrix multiplication has a rule: given matrices $\mathbf{A} \in \mathbb{R}^{j\times k}$ and $\mathbf{B}\in \mathbb{R}^{l \times m}$, the multiplication can only occur if $k = l$, and there will be a resulting matrix $C \in \mathbb{R}^{j \times m}$.
This also applies to dot product? I couldn't really get the difference between these two operations.
Thanks.
