+# gediff
+
+> Calculate the differences between consecutive elements of a one-dimensional ndarray.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var gediff = require( '@stdlib/blas/ext/base/ndarray/gediff' );
+```
+
+#### gediff( arrays )
+
+Calculates the differences between consecutive elements of a one-dimensional ndarray.
+
+```javascript
+var vector = require( '@stdlib/ndarray/vector/ctor' );
+
+var x = vector( [ 2.0, 4.0, 6.0, 8.0, 10.0 ], 'generic' );
+var prepend = vector( [ 1.0 ], 'generic' );
+var append = vector( [ 11.0 ], 'generic' );
+var out = vector( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ], 'generic' );
+
+var y = gediff( [ x, prepend, append, out ] );
+// returns [ 1.0, 2.0, 2.0, 2.0, 2.0, 11.0 ]
+```
+
+The function has the following parameters:
+
+- **arrays**: array-like object containing the following ndarrays:
+
+ - a one-dimensional input ndarray.
+ - a one-dimensional ndarray containing values to prepend prior to computing differences.
+ - a one-dimensional ndarray containing values to append prior to computing differences.
+ - a one-dimensional output ndarray. Must have `N + N1 + N2 - 1` elements, where `N` is the number of elements in the input ndarray, `N1` is the number of elements to prepend, and `N2` is the number of elements to append.
+
+
+
+
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/discrete-uniform' );
+var zeros = require( '@stdlib/ndarray/zeros' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var gediff = require( '@stdlib/blas/ext/base/ndarray/gediff' );
+
+var N = 10;
+var N1 = 2;
+var N2 = 2;
+var opts = {
+ 'dtype': 'generic'
+};
+
+var x = discreteUniform( [ N ], -100, 100, opts );
+var p = discreteUniform( [ N1 ], -100, 100, opts );
+var a = discreteUniform( [ N2 ], -100, 100, opts );
+var out = zeros( [ N + N1 + N2 - 1 ], opts );
+
+console.log( 'x: ', ndarray2array( x ) );
+console.log( 'prepend: ', ndarray2array( p ) );
+console.log( 'append: ', ndarray2array( a ) );
+
+gediff( [ x, p, a, out ] );
+console.log( 'out: ', ndarray2array( out ) );
