Create an array filled with ones and having the same length and data type as a provided array.
var onesLike = require( '@stdlib/array/ones-like' );Creates an array filled with ones and having the same length and data type as a provided array x.
var x = [ 1, 2, 3, 4, 5 ];
var arr = onesLike( x );
// returns [ 1, 1, 1, 1, 1 ]The function supports 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 numberscomplex64: single-precision complex floating-point numbersint32: 32-bit two's complement signed integersuint32: 32-bit unsigned integersint16: 16-bit two's complement signed integersuint16: 16-bit unsigned integersint8: 8-bit two's complement signed integersuint8: 8-bit unsigned integersuint8c: 8-bit unsigned integers clamped to0-255generic: generic JavaScript values
By default, the output array data type is inferred from the provided array x. To return an array having a different data type, provide a dtype argument.
var x = [ 0, 0 ];
var arr = onesLike( x, 'int32' );
// returns <Int32Array>[ 1, 1 ]- If the output array has a complex number data type, each element of the returned array has a real component equal to
1and an imaginary component equal to0.
var dtypes = require( '@stdlib/array/dtypes' );
var zeros = require( '@stdlib/array/zeros' );
var onesLike = require( '@stdlib/array/ones-like' );
// Create a zero-filled array:
var x = zeros( 4, 'complex128' );
// Get a list of array data types:
var dt = dtypes();
// Generate filled arrays...
var y;
var i;
for ( i = 0; i < dt.length; i++ ) {
y = onesLike( x, dt[ i ] );
console.log( y );
