+# gjoinBetween
+
+> Return a string by joining one-dimensional ndarray elements using a specified separator for each pair of consecutive elements.
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var gjoinBetween = require( '@stdlib/blas/ext/base/ndarray/gjoin-between' );
+```
+
+#### gjoinBetween( arrays )
+
+Returns a string by joining one-dimensional ndarray elements using a specified separator for each pair of consecutive elements.
+
+```javascript
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+
+var xbuf = [ 1, 2, 3, 4 ];
+var x = new ndarray( 'generic', xbuf, [ 4 ], [ 1 ], 0, 'row-major' );
+
+var prefix = scalar2ndarray( 'op: ', {
+ 'dtype': 'generic'
+});
+
+var suffix = scalar2ndarray( '', {
+ 'dtype': 'generic'
+});
+
+var sbuf = [ ' + ', ' - ', ' != ' ];
+var separators = new ndarray( 'generic', sbuf, [ 3 ], [ 1 ], 0, 'row-major' );
+
+var out = gjoinBetween( [ x, prefix, suffix, separators ] );
+// returns 'op: 1 + 2 - 3 != 4'
+```
+
+The function has the following parameters:
+
+- **arrays**: array-like object containing the following ndarrays:
+
+ - a one-dimensional input ndarray.
+ - a zero-dimensional ndarray containing a prefix string.
+ - a zero-dimensional ndarray containing a suffix string.
+ - a one-dimensional ndarray containing separator strings.
+
+
+
+
+
+
+
+## Notes
+
+- If the input ndarray is empty, the function returns the prefix and suffix joined together.
+- The `separators` ndarray is assumed to have at least `N-1` elements (i.e., equal to the number of "gaps" between consecutive elements), where `N` is the number of elements in the input ndarray.
+- If an array element is either `null` or `undefined`, the function serializes the element as an empty string.
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var filled = require( '@stdlib/array/base/filled' );
+var ndarray = require( '@stdlib/ndarray/base/ctor' );
+var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
+var ndarray2array = require( '@stdlib/ndarray/to-array' );
+var gjoinBetween = require( '@stdlib/blas/ext/base/ndarray/gjoin-between' );
+
+var xbuf = discreteUniform( 10, -100, 100, {
+ 'dtype': 'generic'
+});
+var x = new ndarray( 'generic', xbuf, [ xbuf.length ], [ 1 ], 0, 'row-major' );
+console.log( ndarray2array( x ) );
+
+var prefix = scalar2ndarray( '[ ', {
+ 'dtype': 'generic'
+});
+
+var suffix = scalar2ndarray( ' ]', {
+ 'dtype': 'generic'
+});
+
+var sbuf = filled( ' | ', xbuf.length - 1 );
+var separators = new ndarray( 'generic', sbuf, [ sbuf.length ], [ 1 ], 0, 'row-major' );
+
+var out = gjoinBetween( [ x, prefix, suffix, separators ] );
+console.log( out );
