Create a flowchart for a UDF that will:

1) Accept input variables for c, L, N, and vector of values x

2) Approximate the step function, f(x), according to the Fourier series provided above, over the input range of x values

3) Return an output variable for a vector of values f(x) (evaluated at each value of x)

Problem 2: Step functions and Fourier series are used in controls aerospace systems. In this problem, you will compute and graph a Fourier series that approximates a step function. The step function shown in figure 1 f(x) 2c 0 2L x Figure 2: Step function can be approximated over the range 0sx2L using the following Fourier series: k=N k-1 where c
