+# sindexOf
+
+> Return the first index of a search element in a one-dimensional single-precision floating-point ndarray.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var sindexOf = require( '@stdlib/blas/ext/base/ndarray/sindex-of' );
+```
+
+#### sindexOf( arrays )
+
+Returns the first index of a specified search element in a one-dimensional single-precision floating-point ndarray.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+var xbuf = new Float32Array( [ 1.0, 3.0, 4.0, 2.0 ] );
+var x = new ndarray( 'float32', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
+
+var searchElement = scalar2ndarray( 2.0, {
+ 'dtype': 'float32'
+});
+
+var fromIndex = scalar2ndarray( 0, {
+ 'dtype': 'generic'
+});
+
+var idx = sindexOf( [ x, searchElement, fromIndex ] );
+// returns 3
+```
+
+The function has the following parameters:
+
+- **arrays**: array-like object containing the following ndarrays:
+
+ - a one-dimensional input ndarray.
+ - a zero-dimensional ndarray containing the search element.
+ - a zero-dimensional ndarray containing the index from which to begin searching.
+
+If the function is unable to find a search element, the function returns `-1`.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+var xbuf = new Float32Array( [ 1.0, 3.0, 4.0, 2.0 ] );
+var x = new ndarray( 'float32', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
+
+var searchElement = scalar2ndarray( 10.0, {
+ 'dtype': 'float32'
+});
+
+var fromIndex = scalar2ndarray( 0, {
+ 'dtype': 'generic'
+});
+
+var idx = sindexOf( [ x, searchElement, fromIndex ] );
+// returns -1
+```
+
+
+
+
+
+
+
+## Notes
+
+- If a specified starting search index is negative, the function resolves the starting search index by counting backward from the last element (where `-1` refers to the last element).
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var ndarraylike2scalar = require( '@stdlib/ndarray/base/ndarraylike2scalar' );
+var sindexOf = require( '@stdlib/blas/ext/base/ndarray/sindex-of' );
+
+var xbuf = discreteUniform( 10, -100, 100, {
+ 'dtype': 'float32'
+});
+var x = new ndarray( 'float32', xbuf, [ xbuf.length ], [ 1 ], 0, 'row-major' );
+console.log( ndarray2array( x ) );
+
+var searchElement = scalar2ndarray( 80.0, {
+ 'dtype': 'float32'
+});
+console.log( 'Search Element:', ndarraylike2scalar( searchElement ) );
+
+var fromIndex = scalar2ndarray( 0, {
+ 'dtype': 'generic'
+});
+console.log( 'From Index:', ndarraylike2scalar( fromIndex ) );
+
+var idx = sindexOf( [ x, searchElement, fromIndex ] );
+console.log( idx );
