+ + + +
+ +## Notes + +- If `M <= 0` or `N <= 0`, both functions return `-1`. +- When searching for a matching row, the function checks for equality using the strict equality operator `===`. As a consequence, `NaN` values are considered distinct, and `-0` and `+0` are considered the same. +- Both functions support array-like objects having getter and setter accessors for array element access (e.g., [`@stdlib/array/base/accessor`][@stdlib/array/base/accessor]). + +
+ + + +
+ +## Examples + + + + + +```javascript +var ndarray2array = require( '@stdlib/ndarray/base/to-array' ); +var shape2strides = require( '@stdlib/ndarray/base/shape2strides' ); +var glastIndexOfRow = require( '@stdlib/blas/ext/base/glast-index-of-row' ); + +var shape = [ 3, 3 ]; +var order = 'row-major'; +var strides = shape2strides( shape, order ); + +var A = [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 4.0, 5.0, 6.0 ]; +console.log( ndarray2array( A, shape, strides, 0, order ) ); + +var x = [ 4.0, 5.0, 6.0 ]; +console.log( x ); + +var out = glastIndexOfRow( order, shape[ 0 ], shape[ 1 ], A, strides[ 0 ], x, 1 ); +console.log( out ); +``` + +
