Write a function with the declaration safe = checkSudoku (board, row, col, num) board is a 4x4 matrix which contains the Sudoku board to check. Unfilled board cells are indicated by a NaN value. row and col are indexes to the check if the number num (between 1 and 4) can be inserted without causing a violation. i.e. does num already exist in the given row, column or 2x2 sub-block. Note that we do not need to check the entire board's validity (although you could try to do so as practice) since we will be filling our board one element at a time. The function returns a logical true or false value in the output safe depending on the outcome of the check. There are several ways to accomplish this functionality. Possible functions you may want to use are sort, unique, ismember, any, all. Note that NaN values are unequal to one another! Test your function with various inputs to see it is operating as expected! For example: >> checkSudoku (unsolvedBoard, 3, 1, 2) ans = 0
