Given an $m\times n$ real or complex matrix $A$ and an $n\times p$ real or complex matrix $B$, this application calculates matrix multiplication $C=AB$ where \[ [C]_{ij} = \sum_{k=1}^{n} [A]_{ik}[B]_{kj}. \] If $p=1$ we get matrix-vector multiplication. If $m=1$ and $p=1$ we get the dot product of two vectors of size $n$.
