+# gfill
+
+> Fill a one-dimensional ndarray with a specified scalar constant.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var gfill = require( '@stdlib/blas/ext/base/ndarray/gfill' );
+```
+
+#### gfill( arrays )
+
+Fills a one-dimensional ndarray with a specified scalar constant.
+
+```javascript
+var vector = require( '@stdlib/ndarray/vector/ctor' );
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+
+var x = vector( [ -2.0, 1.0, 3.0, -5.0, 4.0, -1.0 ], 'generic' );
+
+var alpha = scalar2ndarray( 5.0, {
+ 'dtype': 'generic'
+});
+
+var start = scalar2ndarray( 0, {
+ 'dtype': 'generic'
+});
+
+var end = scalar2ndarray( 3, {
+ 'dtype': 'generic'
+});
+
+gfill( [ x, alpha, start, end ] );
+// x => [ 5.0, 5.0, 5.0, -5.0, 4.0, -1.0 ]
+```
+
+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 scalar constant.
+ - a zero-dimensional ndarray containing the starting index (inclusive).
+ - a zero-dimensional ndarray containing the ending index (exclusive).
+
+
+
+
+
+
+
+## Notes
+
+- The input ndarray is modified **in-place** (i.e., the input ndarray is **mutated**).
+- If a specified `start` or `end` index is negative, the function resolves the respective index by counting backward from the last element (where `-1` refers to the last element).
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/discrete-uniform' );
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var ndarraylike2scalar = require( '@stdlib/ndarray/ndarraylike2scalar' );
+var gfill = require( '@stdlib/blas/ext/base/ndarray/gfill' );
+
+var opts = {
+ 'dtype': 'generic'
+};
+
+var x = discreteUniform( [ 20 ], -100, 100, opts );
+console.log( ndarray2array( x ) );
+
+var alpha = scalar2ndarray( 5, opts );
+console.log( 'Alpha: %d', ndarraylike2scalar( alpha ) );
+
+var start = scalar2ndarray( 5, opts );
+console.log( 'Start Index: %d', ndarraylike2scalar( start ) );
+
+var end = scalar2ndarray( 15, opts );
+console.log( 'End Index: %d', ndarraylike2scalar( end ) );
+
+gfill( [ x, alpha, start, end ] );
+console.log( ndarray2array( x ) );
+```
