Extended BLAS

Extensions to basic linear algebra subprograms (BLAS) compiled to WebAssembly.

Installation

npm install @stdlib/blas-ext-base-wasm

Usage

var ns = require( '@stdlib/blas-ext-base-wasm' );

ns

Namespace for extensions to basic linear algebra subprograms (BLAS) compiled to WebAssembly.

var o = ns;
// returns {...}

• dapx( N, alpha, x, strideX ): add a scalar constant to each element in a double-precision floating-point strided array.
• dapxsum( N, alpha, x, strideX ): add a scalar constant to each double-precision floating-point strided array element and compute the sum.
• dapxsumkbn( N, alpha, x, strideX ): add a scalar constant to each double-precision floating-point strided array element and compute the sum using an improved Kahan–Babuška algorithm.
• dapxsumors( N, alpha, x, strideX ): add a scalar constant to each double-precision floating-point strided array element and compute the sum using ordinary recursive summation.
• dapxsumpw( N, alpha, x, strideX ): add a scalar constant to each double-precision floating-point strided array element and compute the sum using pairwise summation.
• dasumpw( N, x, strideX ): calculate the sum of absolute values (L1 norm) of double-precision floating-point strided array elements using pairwise summation.
• dnanasumors( N, x, strideX ): calculate the sum of absolute values (L1 norm) of double-precision floating-point strided array elements, ignoring NaN values and using ordinary recursive summation.
• dnansumkbn2( N, x, strideX ): calculate the sum of double-precision floating-point strided array elements, ignoring NaN values and using a second-order iterative Kahan–Babuška algorithm.
• dnansumpw( N, x, strideX ): calculate the sum of double-precision floating-point strided array elements, ignoring NaN values and using pairwise summation.
• sapxsumkbn( N, alpha, x, strideX ): add a scalar constant to each single-precision floating-point strided array element and compute the sum using an improved Kahan–Babuška algorithm.

Examples

var objectKeys = require( '@stdlib/utils-keys' );
var ns = require( '@stdlib/blas-ext-base-wasm' );

console.log( objectKeys( ns ) );
