f06bn returns the value $\sqrt{a^2+b^2}$.

f06db broadcasts an integer scalar into an integer vector.

f06ea computes the scalar product of two real vectors.

f06ef makes a copy of a real vector .

f06ej returns the Euclidean norm of the $n$-element real vector $x$.

f06fd multiplies a real vector by a scalar, preserving the input vector.

f06jj computes the Euclidean norm of a complex vector.

f06pa computes the matrix-vector product for a real general matrix or its transpose.

f06pj solves a real triangular system of equations with a single right hand side.

f06qf performs the matrix-copy operation where $A$ and $B$ are $m$ by $n$ real general or trapezoidal matrices.

f06qh forms the real $m$ by $n$ rectangular or trapezoidal matrix $A$ given by

f06ya performs one of the matrix-matrix operations where $A$, $B$ and $C$ are real matrices, and $\alpha$ and $\beta$ are real scalars; $C$ is always $m$ by $n$.

f06yj performs one of the matrix-matrix operations where $A$ is a real triangular matrix, $B$ is an $m$ by $n$ real matrix, and $\alpha$ is a real scalar. $A^{-\mathrm{T}}$ denotes ${\left(A^{\mathrm{T}}\right)}^{-1}$ or equivalently ${\left(A^{-1}\right)}^{\mathrm{T}}$.

No test for singularity or near-singularity of $A$ is included in this method. Such tests must be performed before calling this method.
