function isFloat64MatrixLike( v ) {
	return ( isMatrixLike( v ) && v.dtype === 'float64' );
}
Tests if a value is a 2-dimensional ndarray-like object whose underlying data type is `float64`.

@param {*} v - value to test
@returns {boolean} boolean indicating if a value is a 2-dimensional ndarray-like object whose underlying data type is `float64`

@example
var Float64Array = require( '@stdlib/array/float64' );
var ndarray = require( '@stdlib/ndarray/ctor' );

var buffer = new Float64Array( [ 0, 0, 0, 0 ] );
var arr = ndarray( 'float64', buffer, [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );

var bool = isFloat64MatrixLike( arr );
// returns true

bool = isFloat64MatrixLike( [] );
// returns false
