{{alias}}( N, x, strideX, y, strideY )
Computes the cumulative minimum of double-precision floating-point strided
array elements.
The `N` and `stride` parameters determine which elements in `x` and `y` are
accessed at runtime.
Indexing is relative to the first index. To introduce an offset, use a typed
array view.
If `N <= 0`, the function returns `y` unchanged.
Parameters
----------
N: integer
Number of indexed elements.
x: Float64Array
Input array.
strideX: integer
Index increment for `x`.
y: Float64Array
Output array.
strideY: integer
Index increment for `y`.
Returns
-------
out: Float64Array
Output array.
Examples
--------
// Standard Usage:
> var x = new {{alias:@stdlib/array/float64}}( [ 1.0, -2.0, 2.0 ] );
> var y = new {{alias:@stdlib/array/float64}}( x.length );
> {{alias}}( x.length, x, 1, y, 1 )
<Float64Array>[ 1.0, -2.0, -2.0 ]
// Using `N` and `stride` parameters:
> x = new {{alias:@stdlib/array/float64}}( [ -2.0, 1.0, 1.0, -5.0, 2.0, -1.0 ] );
> y = new {{alias:@stdlib/array/float64}}( x.length );
> var N = {{alias:@stdlib/math/base/special/floor}}( x.length / 2 );
> {{alias}}( N, x, 2, y, 2 )
<Float64Array>[ -2.0, 0.0, -2.0, 0.0, -2.0, 0.0 ]
// Using view offsets:
> var x0 = new {{alias:@stdlib/array/float64}}( [ 1.0, -2.0, 3.0, 2.0, 5.0, -1.0 ] );
> var y0 = new {{alias:@stdlib/array/float64}}( x0.length );
> var x1 = new {{alias:@stdlib/array/float64}}( x0.buffer, x0.BYTES_PER_ELEMENT*1 );
> var y1 = new {{alias:@stdlib/array/float64}}( y0.buffer, y0.BYTES_PER_ELEMENT*3 );
> N = {{alias:@stdlib/math/base/special/floor}}( x0.length / 2 );
> {{alias}}( N, x1, 2, y1, 1 )
<Float64Array>[ -2.0, -2.0, -2.0 ]
> y0
<Float64Array>[ 0.0, 0.0, 0.0, -2.0, -2.0, -2.0 ]
{{alias}}.ndarray( N, x, strideX, offsetX, y, strideY, offsetY )
Computes the cumulative minimum of double-precision floating-point strided
array elements using alternative indexing semantics.
While typed array views mandate a view offset based on the underlying
buffer, the `offset` parameter supports indexing semantics based on a
starting index.
Parameters
----------
N: integer
Number of indexed elements.
x: Float64Array
Input array.
strideX: integer
Index increment for `x`.
offsetX: integer
Starting index for `x`.
y: Float64Array
Output array.
strideY: integer
Index increment for `y`.
offsetY: integer
Starting index for `y`.
Returns
-------
out: Float64Array
Output array.
Examples
--------
// Standard Usage:
> var x = new {{alias:@stdlib/array/float64}}( [ 1.0, -2.0, 2.0 ] );
> var y = new {{alias:@stdlib/array/float64}}( x.length );
> {{alias}}.ndarray( x.length, x, 1, 0, y, 1, 0 )
<Float64Array>[ 1.0, -2.0, -2.0 ]
// Advanced indexing:
> x = new {{alias:@stdlib/array/float64}}( [ 1.0, -2.0, 3.0, 2.0, 5.0, -1.0 ] );
> y = new {{alias:@stdlib/array/float64}}( x.length );
> var N = {{alias:@stdlib/math/base/special/floor}}( x.length / 2 );
> {{alias}}.ndarray( N, x, 2, 1, y, -1, y.length-1 )
<Float64Array>[ 0.0, 0.0, 0.0, -2.0, -2.0, -2.0 ]
