Use matlab or octave to code. DO NOT USE if statements, while or for loops, reshape or randperm commands. Only use vectors, matrices, functions or graph built-in functions

6. (Simple function plotting) Often, we wish to plot a given function f which is already coded in MATLAB in such a way that it is able to work on a vector of inputs and produce a vector of outputs (such as the built-in sin function). We may wish to plot it on a given interval [a, b] and using a particular spacing. plot_func Function: Input variables: an anonymous function representing f a scalar representing a a scalar representing b an integer scalar n representing that we wish to use a spacing between our r points of 6-2 Plots produced: produce a single plot of f at the desired inputs Output variables: a vector representing the values of f at each of the desired inputs . . A possible sample case is: >> y = plot_func(@(x) x.^2 + 1, -3, 3, 6) y = 10 5 2 1 2 5 10 . m2 a scalar representing b an integer scalar n representing that we wish to use a spacing between our x points of b-a Plots produced: produce a single plot of f at the desired inputs Output variables: a vector representing the values of f at each of the desired inputs A possible sample case is: . >> y = plot_func(@(x) x.^2 + 1, -3, 3, 6) y = 10 5 2 1 2 5 10
