pymath.determinant

Returns the determinant of a square matrix.

d = pymath.determinant(A)

Parameter	Type	Description
A	matrix	A square matrix (n × n), represented as an array of n row-vectors.

Return value

Type	Description
d	The determinant of A as a number.

Notes:

• A must be square, otherwise an error is raised.

Example:

local A = {{4, 7},
           {2, 6}}
local d = pymath.determinant(A)
-- d == 10

local S = {{1, 2},
           {2, 4}}        -- singular
local ds = pymath.determinant(S)
-- ds == 0
