import { Matrix } from '../types';
/**
* Generates a matrix based on input `mx` but excluding items based on their modulo and their
* position in the original matrix.
*
* It's a crude implementation of Matlab's `A(1:f:end,1:f:end)` syntax where the first parameter
* is the matrix, the next one is an array describing the rows to skip [start position, every `f`
* elements an end position] and the last one follows the same syntax for columns.
*
* @example
* ```
* img1(1:f:end,1:f:end)
*
* ```
*
* becomes:
*
* ```
* skip2d(img1, [0, f, img1.length], [0, f, img1[0].length])
* ```
*
* Note that the start index is 0 since, unlike Matlab's, arrays start at 0. Also, unlike in Matlab,
* `f` must be an integer greater than or equal to 1.
*
* @method skip2d
* @param {Matrix} A - The input matrix
* @param {Array<number>} - start row, every row, end row
* @param {Array<number>} - start col, every col, end col
* @returns {Matrix} B - The downsized matrix
* @public
* @memberOf matlab
* @since 0.0.2
