The F07 type exposes the following members.

Methods

  NameDescription
f07ab
f07ab uses the LU factorization to compute the solution to a real system of linear equations
AX=B  or  ATX=B,
where A is an n by n matrix and X and B are n by r matrices. Error bounds on the solution and a condition estimate are also provided.
f07ap
f07ap uses the LU factorization to compute the solution to a complex system of linear equations
AX=B  or  ATX=B  or  AHX=B,
where A is an n by n matrix and X and B are n by r matrices. Error bounds on the solution and a condition estimate are also provided.
f07ar
f07ar computes the LU factorization of a complex m by n matrix.
f07as
f07as solves a complex system of linear equations with multiple right-hand sides,
AX=B, ATX=B  or  AHX=B,
where A has been factorized by f07ar.
f07fb
f07fb uses the Cholesky factorization
A=UTU  or  A=LLT
to compute the solution to a real system of linear equations
AX=B,
where A is an n by n symmetric positive definite matrix and X and B are n by r matrices. Error bounds on the solution and a condition estimate are also provided.
f07fp
f07fp uses the Cholesky factorization
A=UHU  or  A=LLH
to compute the solution to a complex system of linear equations
AX=B,
where A is an n by n Hermitian positive definite matrix and X and B are n by r matrices. Error bounds on the solution and a condition estimate are also provided.
