naginterfaces.library.blas.zmcopy

naginterfaces.library.blas.zmcopy(matrix, m, a)

zmcopy performs the matrix-copy operation

$$B\leftarrow A$$

where $A$ and $B$ are $m\times n$ complex general or trapezoidal matrices.

Parameters

matrixstr, length 1

The matrix type.

$matrix=\text{'G'}$

General matrix.

$matrix=\text{'U'}$

Upper trapezoidal matrix (upper triangular if $m=n$).

$matrix=\text{'L'}$

Lower trapezoidal matrix (lower triangular if $m=n$).

mint

$m$, the number of rows of the matrices $A$ and $B$.

acomplex, array-like, shape $(m,n)$

The $m\times n$ general or trapezoidal matrix $A$.

Returns

bcomplex, ndarray, shape $(m,n)$

The $m\times n$ general or trapezoidal matrix $B$.

Raises

NagValueError

(errno $1$)

On entry, error in parameter $matrix$.

Constraint: $matrix=\text{'G'}$, $\text{'U'}$ or $\text{'L'}$.

(errno $2$)

On entry, error in parameter $m$.

Constraint: $m\ge 0$.

(errno $3$)

On entry, error in parameter $\text{n}$.

Constraint: $n\ge 0$.

Notes

No equivalent traditional C interface for this routine exists in the NAG Library.
