For example, to compare every other element in `x` to every other element in `y`: + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 0.0, 0.0, 1.0, 0.0, 0.0, 0.0 ] ); +var y = new Float32Array( [ 0.0, 0.0, 1.0, 0.0, 9.0, 0.0 ] ); + +var idx = sfirstIndexNotEqual( 3, x, 2, y, 2 ); +// returns 2 +``` + +Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views. + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +// Initial arrays... +var x0 = new Float32Array( [ 0.0, 0.0, 0.0, 1.0, 0.0, 0.0 ] ); +var y0 = new Float32Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] ); + +// Create offset views... +var x1 = new Float32Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element +var y1 = new Float32Array( y0.buffer, y0.BYTES_PER_ELEMENT*1 ); // start at 2nd element + +var idx = sfirstIndexNotEqual( x1.length, x1, 1, y1, 1 ); +// returns 2 +``` + +#### sfirstIndexNotEqual.ndarray( N, x, strideX, offsetX, y, strideY, offsetY ) + +Returns the index of the first element in a single-precision floating-point strided array which is not equal to the corresponding element in another single-precision floating-point strided array using alternative indexing semantics. + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 0.0, 0.0, 1.0, 0.0 ] ); +var y = new Float32Array( [ 0.0, 0.0, 0.0, 0.0 ] ); + +var idx = sfirstIndexNotEqual.ndarray( x.length, x, 1, 0, y, 1, 0 ); +// returns 2 +``` + +The function has the following additional parameters: + +- **offsetX**: starting index for `x`. +- **offsetY**: starting index for `y`. + +While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameters support indexing semantics based on starting indices. For example, to compare the last three elements of `x` to the last three elements of `y`: + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 0.0, 0.0, 0.0, 1.0 ] ); +var y = new Float32Array( [ 1.0, 0.0, 0.0, 0.0 ] ); + +var idx = sfirstIndexNotEqual.ndarray( 3, x, 1, x.length-3, y, 1, y.length-3 ); +// returns 2 +``` + +
+ + + + + +
+ +## Notes + +- If `N <= 0`, both functions return `-1`. +- Both functions determine whether corresponding elements are equal using strict equality (i.e., the `===` operator). As a consequence, `NaN` values are considered distinct, and `-0` and `+0` are considered the same. + +
+ + + + + +
+ +## Examples + + + +```javascript +var discreteUniform = require( '@stdlib/random/array/discrete-uniform' ); +var sfirstIndexNotEqual = require( '@stdlib/blas/ext/base/sfirst-index-not-equal' ); + +var opts = { + 'dtype': 'float32' +}; +var x = discreteUniform( 10, 0, 10, opts ); +console.log( x ); + +var y = discreteUniform( 10, 0, 10, opts ); +console.log( y ); + +var idx = sfirstIndexNotEqual( x.length, x, 1, y, 1 ); +console.log( idx ); +``` + +
