b) Make a script file 'date.m' with which the user can call up de desired date. How to solve the problem - Ask the user (with the command >> input if he/she wants to know the date (1=yes, 2=no). - If the answer is 'yes' the date must be displayed (>> date). - If the answer is 'no' display on the screen that the user does not want to know the date (>> disp) Write the m-file in MATLAB. c) Given the function prototype, Function [out]= examfen (in) Write four (4) different calls to the function, each of which uses a distinctly different method to provide a value for the required parameter. Assume any variables that you need are available
