Styles 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 x x6 x3 x5 f(x) = 1+x+ + + + + 2! 3! 4! 5! 6! (b) (5 points) Test your UDF function "simpleE" from (a) for x=0.65, call it fsimple = f(0.65). (c) (8 points) Use Matlab built-in function to calculate the exponential value: ferace = 0.65 and compute the absolute difference between fsimple and fexact. (hint: you can use Matlab function "abs" to compute the absolute difference)
