Matrix arithmetic
You can use the arithmetic functions (+, –, ×, / and
powers) with matrix arguments. Division left-multiplies by
the inverse of the divisor. You can enter the matrices
themselves or enter the names of stored matrix variables.
The matrices can be real or complex.
For the next examples, store [[1,2],[3,4]] into M1 and
[[5,6],[7,8]] into M2.
Example 1. Create the first matrix.
