For example, to count every other element in `x` starting from the second element, + +```javascript +var Complex128Array = require( '@stdlib/array/complex128' ); + +var x = new Complex128Array( [ 2.0, 1.0, NaN, -2.0, 3.0, 4.0, NaN, NaN ] ); + +var v = znancount.ndarray( 2, x, 2, 1 ); +// returns 0 +``` + +
