determinant
calculates the determinant (or its logarithm) of a matrix
## S3 method for class 'Matrix': determinant(x, logarithm = TRUE, ...)
x |
numeric matrix. |
logarithm |
logical.
When TRUE , the default, the logarithm of the
determinant is returned.
When FALSE , the determinant of
x is returned.

determinant
is a generic function with special methods for different types
of matrices or decompositions.
Use methods("determinant")
to list all the methods for the
determinant
generic.
determinant
return a list with two elements
modulus |
a numeric value. The modulus (absolute value) of
the determinant or the logarithm of the modulus. The value
of the logarithm argument is included as an
attribute. |
sign |
a numeric value, which is +/- 1 according to whether the determinant is positive or negative. |

Often, computing the determinant is not what you should be doing to solve a given problem.
