function setter( dtype ) {
	var f = SETTERS[ dtype ];
	if ( typeof f === 'function' ) {
		return f;
	}
	return SETTERS.default;
}
Returns an accessor function for setting an element in an array-like object supporting the get/set protocol.

@param {string} dtype - array dtype
@returns {Function} accessor

@example
var Complex64Array = require( '@stdlib/array/complex64' );
var Complex64 = require( '@stdlib/complex/float32/ctor' );
var realf = require( '@stdlib/complex/float32/real' );
var imagf = require( '@stdlib/complex/float32/imag' );
var dtype = require( '@stdlib/array/dtype' );

var arr = new Complex64Array( [ 1, 2, 3, 4 ] );

var set = setter( dtype( arr ) );
set( arr, 1, new Complex64( 10.0, 11.0 ) );

var v = arr.get( 1 );
// returns <Complex64>

var re = realf( v );
// returns 10.0

var im = imagf( v );
// returns 11.0
