Inputs
Outputs
Generic word contract
Compute the determinant of the input matrix. Generally, the determinant of a matrix is a scaling factor of the transformation described by the matrix.
Notes
Errors
non-square-determinant if the input matrix is not a square-matrix.

Inputs
| matrix | a square-matrix |
Outputs
| determinant | a number |
Generic word contract
Compute the determinant of the input matrix. Generally, the determinant of a matrix is a scaling factor of the transformation described by the matrix.
Notes
| • | This word is intended for use with "flat" (2-dimensional) matrices. |
| • | This word assumes that elements of the input matrix are compatible with the following words: max ( obj1 obj2 -- obj ) - ( x y -- z ) * ( x y -- z ) |
Errors
non-square-determinant if the input matrix is not a square-matrix.
