5 Arguments

1: $\mathbf{m}$ – Integer Input

On entry: the number of Hermitian sequences to be conjugated, $m$.

Constraint: $\mathbf{m}\ge 1$.

2: $\mathbf{n}$ – Integer Input

On entry: the number of data values in each Hermitian sequence, $n$.

Constraint: $\mathbf{n}\ge 1$.

3: $\mathbf{x}\left[\mathbf{m}\times \mathbf{n}\right]$ – double Input/Output

On entry: the $m$ data sequences must be stored in x consecutively. If the $n$ data values $z_j^p$ are written as $x_j^p+{iy}_j^p$, $p=1,2,\dots ,m$, then for $0\le j\le n/2$, $x_j^p$ is contained in $\mathbf{x}\left[\left(p-1\right)\times n+j\right]$, and for $1\le j\le \left(n-1\right)/2$, $y_j^p$ is contained in $\mathbf{x}\left[\left(p-1\right)\times n+n-j\right]$.

On exit: the imaginary parts $y_j^p$ are negated. The real parts $x_j^p$ are not referenced.

4: $\mathbf{fail}$ – NagError * Input/Output

The NAG error argument (see Section 7 in the Introduction to the NAG Library CL Interface).

6 Error Indicators and Warnings
