| det {base} | R Documentation |
det calculates the determinant of a matrix. determinant
is a generic function that returns separately the modulus of the determinant,
optionally on the logarithm scale, and the sign of the determinant.

The determinant function
uses an LU decomposition and the det function is simply a
wrapper around a call to determinant.
Often, computing the determinant is not what you should be doing to solve a given problem.
For det, the determinant of x. For determinant, a
