Extended BLAS

Extended basic linear algebra subprograms (BLAS).

Installation

npm install @stdlib/blas-ext

Usage

var extblas = require( '@stdlib/blas-ext' );

extblas

Namespace for extended basic linear algebra subprograms (BLAS).

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

The namespace contains the following:

• base: base (i.e., lower-level) extensions to basic linear algebra subprograms (BLAS).
• cusum( x[, initial][, options] ): compute the cumulative sum along one or more ndarray dimensions.
• findIndex( x[, options], clbk[, thisArg] ): return the index of the first element along an ndarray dimension which passes a test implemented by a predicate function.
• findLastIndex( x[, options], clbk[, thisArg] ): return the index of the last element along an ndarray dimension which passes a test implemented by a predicate function.
• indexOf( x, searchElement[, fromIndex][, options] ): return the first index of a specified search element along an ndarray dimension.
• lastIndexOf( x, searchElement[, fromIndex][, options] ): return the last index of a specified search element along an ndarray dimension.
• linspace( shape, start, stop[, endpoint][, options] ): return a new ndarray filled with linearly spaced values over a specified interval along one or more ndarray dimensions.
• sorthp( x[, sortOrder][, options] ): sort an input ndarray along one or more ndarray dimensions using heapsort.
• sum( x[, options] ): compute the sum along one or more ndarray dimensions.
• toSortedhp( x[, sortOrder][, options] ): return a new ndarray containing the elements of an input ndarray sorted along one or more ndarray dimensions using heapsort.

Examples

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

console.log( objectKeys( ns ) );
