## Matrix Addition Calculator

Given two $m\times n$ real or complex matrices $A$ and $B$ and two real or complex scalars $\alpha$, $\beta$ this application calculate \[\alpha A+\beta B\] If $\alpha=1$, $\beta=1$ and $\beta=-1$ we get $A+B$ and $A-B$, respectively. By setting $\beta=0$ we obtain $\alpha A$, i.e. multiplying matrix $A$ with scalar $\alpha$. The input formats for scalars $\alpha$ and $\beta$ are the same as matrix entries as described in Input Data, i.e. they can be entered as numbers or mathematical expressions.
