Dividing by a square matrix
For division of a matrix or a vector by a square matrix, the number of rows of the dividend (or the number of
elements, if it is a vector) must equal the number of rows in the divisor.
This operation is not a mathematical division: it is a left multiplication by the inverse of the divisor. M1/M2 is
equivalent to M2
–1
* M1.
To divide the two matrices you created for the previous example, press the following keys:

Inverting a matrix
You can invert a square matrix in Home view by typing the matrix (or its variable name) and pressing
. You can also use the INVERSE command in the Matrix category of the Math menu.
