function iladlr( M, N, A, strideA1, strideA2, offsetA ) {
	return base( M, N, A, strideA1, strideA2, offsetA );
}
Returns the index of the last non-zero row in a matrix `A` using alternative indexing semantics.

@param {PositiveInteger} M - number of rows in `A`
@param {PositiveInteger} N - number of columns in `A`
@param {Float64Array} A - input matrix
@param {integer} strideA1 - stride of the first dimension of `A`
@param {integer} strideA2 - stride of the second dimension of `A`
@param {NonNegativeInteger} offsetA - index offset for `A`
@returns {integer} index of the last non-zero row

@example
var Float64array = require( '@stdlib/array/float64' );

var A = new Float64array( [ 1.0, 2.0, 3.0, 4.0, 0.0, 0.0 ] ); // => [ [ 1.0, 2.0 ], [ 3.0, 4.0 ], [ 0.0, 0.0 ] ]

var out = iladlr( 3, 2, A, 2, 1, 0 );
// returns 1
