Please I need help with writing this matlab code for question 1.b), so please help me with this also please include comments explaining the code and providing detail to it that explains what is do what and what does this variable represents, etc.

b) Write MATLAB code that takes as input a positive parameter k and a desired error threshold err, and returns the first value n so that the nth-order Taylor Polynomial for f(x)=ekx about x=0 is within err of ekx for all x[1,1]. Use your code to reproduce your answer to question 1 (a). HINT: Your code does not need to be fancy at all! By mimicking your theoretical analysis from 1(a), the computational challenge in finding the correct value for n should be quite elementary
