/**
* Returns the index of the first column in an input matrix which has the same elements as a provided search vector using alternative indexing semantics.
*
* ## Notes
*
* - If the function is provided an empty matrix or if the function is unable to find a search vector, 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 {Collection} 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`
* @param {Collection} x - search vector
* @param {integer} strideX - stride length for `x`
* @param {NonNegativeInteger} offsetX - index offset for `x`
* @returns {integer} column index
*
* @example
* var A = [ 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 x = [ 2.0, 4.0, 0.0 ];
*
* var out = gindexOfColumn( 3, 2, A, 2, 1, 0, x, 1, 0 );
* // returns 1
