with matlab

3- (25 points) User Defined Function (UDF): (use long format for this question) a) (12 points) The simplified exponential function is defined as following. Write a UDF function, name it simpleE", that has one input and one output x2x3 x" x5 f(x) = 1 +*+ + 21 31 + + 41 5! 61 (b) (5 points) Test your UDF function "simple from () for x = 0.65, call it forple = f(0.65) (c) (8 points) Use Matlab built-in function to calculate the exponential value: Sexace = 465, and compute the absolute difference between friends and forest (hint: you can use Matlab function "abs" to compute the absolute difference)
