The QGenericMatrix class is a template class that represents a NxM transformation matrix with N columns and M rows.
The QGenericMatrix template has three parameters:
| N | Number of columns. |
| M | Number of rows. |
| T | Element type that is visible to users of the class. |

Returns true if this matrix is the identity; false otherwise.
See also setToIdentity().
Sets this matrix to the identity.
See also isIdentity().
Returns this matrix, transposed about its diagonal.
Returns true if this matrix is not identical to other; false otherwise.

Adds the contents of other to this matrix.
Subtracts the contents of other from this matrix.
Divides all elements of this matrix by divisor.
Returns true if this matrix is identical to other; false otherwise.
