?copy_batch_strided

Computes a group of vector copies.

Syntax

call scopy_batch_strided(n, x, incx, stridex, y, incy, stridey, batch_size)

call dcopy_batch_strided(n, x, incx, stridex, y, incy, stridey, batch_size)

call ccopy_batch_strided(n, x, incx, stridex, y, incy, stridey, batch_size)

call zcopy_batch_strided(n, x, incx, stridex, y, incy, stridey, batch_size)

Description

The ?copy_batch_stridedcblas_?copy_batch_strided routines perform a series of vector copies. They are similar to their ?copycblas_?copy routine counterparts, but the ?copy_batch_stridedcblas_?copy_batch_strided routines perform vector operations with a group of vectors.

All vectors x (respectively, y ) have the same parameters (size, increment) and are stored at constant distance stridex (respectively, stridey ) from each other. The operation is defined as follows:

for i = 0 … batch_size – 1
    X and Y are vectors at offset i * stridex and i * stridey in x and y
    Y = X
end for

Input Parameters

n: INTEGER. Number of elements in vectors x and y .
x: REAL for scopy_batch_strided DOUBLE PRECISION for dcopy_batch_strided COMPLEX for ccopy_batch_strided DOUBLE COMPLEX for zcopy_batch_strided Array of size at least stridex*batch_size holding the input x vectors.
incx: INTEGER. Specifies the increment between two consecutive elements of a single vector x .
stridex: INTEGER. Stride between two consecutive x vectors. Must be at least (1 + (n-1)*abs(incx)) .
y: REAL for scopy_batch_strided DOUBLE PRECISION for dcopy_batch_strided COMPLEX for ccopy_batch_strided DOUBLE COMPLEX for zcopy_batch_strided Array of size at least stridey*batch_size holding the output y vectors.
incy: INTEGER. Specifies the increment between two consecutive elements of a single vector y .
stridey: INTEGER. Stride between two consecutive y vectors. Must be at least (1 + (n-1)*abs(incy)) .
batch_size: INTEGER. Number of copy computations to perform and x and y vectors. Must be at least 0.

Output Parameters

y: Array holding the batch_size copied vectors y .
