Computes pzeudo Zernike radial polynomials using the hybrid method mentioned

f the input is a numeric array, it returns a cell array of strings of on or off depending on the logical outcome. Conversely, if the input is a cell array of strings of on or off , then it does the reverse, i.e. returns the logical matrix where on is true and off is false. It is very useful when using set/get on arrays of handle objects or arrays of properties/values. Example: onoff( [0, 1, 0]) gives { off , on , off } onoff({ on , on , off }) gives [1, 1, 0] It also works for mixed cell array inputs, and for other string pairs: yes/no, ok/cancel, open/closed
