squareMatrix Tolerance
det( [,
Returns the determinant of squareMatrix.
Optionally, any matrix element is treated as zero if its absolute value
is less than Tolerance. This tolerance is used only if the matrix has
floating-point entries and does not contain any symbolic variables
that have not been assigned a value. Otherwise, Tolerance is
ignored.

• If you use
mode to Approximate, computations are done using floating-
point arithmetic.
If Tolerance is omitted or not used, the default tolerance is
