Export assignment dispatch

• dispatch(table: Table): DispatchFunction

• Returns a function which dispatches to specified functions based on input argument types.

  throws

  must provide valid table fields

  throws

  table field values must be array-like objects having an even number of elements

  throws

  table field values must consist of dtype-function pairs

  Parameters

  • table: Table

    resolution table object

  Returns DispatchFunction

  dispatch function

  Example

  var nabs = require( `@stdlib/math/base/special/abs` );
  var dabs = require( `@stdlib/math/strided/special/dabs` );
  var sabs = require( `@stdlib/math/strided/special/sabs` );
  var gabs = require( `@stdlib/math/strided/special/abs` );
  var Float64Array = require( `@stdlib/array/float64` );
  
  var table = {
      'scalar': [
          'number', nabs
      ],
      'array': [
          'float64', dabs,
          'float32', sabs,
          'generic', gabs
      ],
      'ndarray': [
          'float64', dabs.ndarray,
          'float32', sabs.ndarray,
          'generic', gabs.ndarray
      ]
  };
  
  var abs = dispatch( table );
  
  var x = new Float64Array( [ -1.0, -2.0, -3.0 ] );
  var y = abs( x );
  // returns <Float64Array>[ 1.0, 2.0, 3.0 ]
