lu {Matrix} | R Documentation |
Computes triangular decompositions of matrices.
lu(x, ...)
x |
a matrix. No missing values or IEEE special values are allowed. |

additional arguments, such as choosing lower or upper triangular factors in the Hermitian case. |
This is a generic function with special methods for different types
of matrices.
Use methods("lu")
to list all the methods for the
lu
generic.
