    ones

    NPM version Build Status Coverage Status

    Create an array filled with ones and having a specified length.

    Installation

    npm install @stdlib/array-ones

    Usage

    var ones = require( '@stdlib/array-ones' );

    ones( length[, dtype] )

    Creates an array filled with ones and having a specified length.

    var arr = ones( 2 );
    // returns <Float64Array>[ 1.0, 1.0 ]

    The function recognizes the following data types:

    • float64: double-precision floating-point numbers (IEEE 754)
    • float32: single-precision floating-point numbers (IEEE 754)
    • complex128: double-precision complex floating-point numbers
    • complex64: single-precision complex floating-point numbers
    • int32: 32-bit two's complement signed integers
    • uint32: 32-bit unsigned integers
    • int16: 16-bit two's complement signed integers
    • uint16: 16-bit unsigned integers
    • int8: 8-bit two's complement signed integers
    • uint8: 8-bit unsigned integers
    • uint8c: 8-bit unsigned integers clamped to 0-255
    • generic: generic JavaScript values

    By default, the output array data type is float64 (i.e., a typed array). To specify an alternative data type, provide a dtype argument.

    var arr = ones( 2, 'int32' );
    // returns <Int32Array>[ 1, 1 ]

    Notes

    • For complex number arrays, each entry of the returned array has a real component equal to 1 and an imaginary component equal to 0.

    Examples

    var dtypes = require( '@stdlib/array-dtypes' );
    var ones = require( '@stdlib/array-ones' );
    
    // Get a list of array data types:
    var dt = dtypes();
    
    // Generate filled arrays...
    var arr;
    var i;
    for ( i = 0; i < dt.length; i++ ) {
        arr = ones( 4, dt[ i ] );
        console.log( arr );
    }

    Notice

    This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
