* Computes the dot product of two single-precision floating-point vectors with extended accumulation.
|
|
*
|
|
* @param {PositiveInteger} N - number of values over which to compute the dot product
|
|
* @param {number} scalar - scalar constant to add to dot product
|
|
* @param {Float32Array} x - first input array
|
|
* @param {integer} strideX - `x` stride length
|
|
* @param {Float32Array} y - second input array
|
|
* @param {integer} strideY - `y` stride length
|
|
* @returns {number} dot product of `x` and `y`
|
|
*
|
|
* @example
|
|
* var Float32Array = require( '@stdlib/array/float32' );
|
|
*
|
|
* var x = new Float32Array( [ 4.0, 2.0, -3.0, 5.0, -1.0 ] );

|
|
*
|
|
* var z = sdsdot( x.length, 0.0, x, 1, y, 1 );

* // returns -5.0
