{{alias}}( N, x, strideX, y, strideY )
|
|
Copies values from one complex single-precision floating-point vector to
|
|
another complex single-precision floating-point vector.
|
|
|
|
The `N` and `stride` parameters determine how values from `x` are copied
|
|
into `y`.
|
|
|
|
Indexing is relative to the first index. To introduce an offset, use typed
|
|
array views.
|
|
|
|
If `N` is less than or equal to `0`, the function returns `y` unchanged.
|
|
|
|
Parameters
|
|
----------
|
|
N: integer
|
|
Number of values to copy.
|
|
|
|
x: Complex64Array
|
|
Input array.
|
|
|
|
strideX: integer
|
|
Index increment for `x`.
|
|
|
|
y: Complex64Array
|
|
Destination array.
|
|
|
|
strideY: integer
|
|
Index increment for `y`.
|
|
|
|
Returns
|
|
-------
|
|
y: Complex64Array
|
|
Input array `y`.

{{alias}}.ndarray( N, x, strideX, offsetX, y, strideY, offsetY )
|
|
Copies values from one complex single-precision floating-point vector to
|
|
another complex single-precision floating-point vector using alternative
|
|
indexing semantics.
|
|
|
|
While typed array views mandate a view offset based on the underlying
|
|
buffer, the `offset` parameters support indexing semantics based on starting
|
|
indices.
|
|
|
|
Parameters
|
|
----------
|
|
N: integer
|
|
Number of values to copy.
|
|
|
|
x: Complex64Array
|
|
Input array.
|
|
|
|
strideX: integer
|
|
Index increment for `x`.
|
|
|
|
offsetX: integer
|
|
Starting index for `x`.
|
|
|
|
y: Complex64Array
|
|
Destination array.
|
|
|
|
strideY: integer
|
|
Index increment for `y`.
|
|
|
|
offsetY: integer
|
|
Starting index for `y`.
|
|
|
|
Returns
|
|
-------
|
|
y: Complex64Array
|
|
Input array `y`.
