USE MATLAB PLEASE! I NEED QUESTION NUMBER 2!

Create m-functions (STRICTLY FUNCTIONS NOT REGULAR SCRIPTS!) 1) Take a numerical input and an alphabet from the user, then convert this numerical input into temperature in Celsius or in Fahrenheit based on the alphabet. (i.e input [32, F]=> output [0, C]). The result should be delivered to the main workspace. 2) Take three numbers and an alphabet from the user, then converting the number into Coordinate to other two Coordinate Systems. (i.e input [##,##,##,C] => output [##,##,##,Y], [##,##,##,S]). (USE Y for Cyndrical Coordinate System). The result should be delivered in the main workspace
