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

## Notes

-   If provided an empty matrix or a matrix containing only zeros, the function returns `-1` (i.e., an invalid index).

@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 column

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

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

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