Question

Can I please have help fixing my matlab code. I have attached all the work leading up to it along with the question itself. I need help with the code since i dont believe it is correct and i get some errors when i run the code. The code is also incomplete so could you help me complete it. Could it please be typed because some handwriting is really hard to understand. Thank you.

%MatLab code for first half of the graphs:

Consider a Hilbert space, H, a complete orthogonal set, B, where B = {bi,b2,by, this chapter, it was shown that ) H and VBcH In ! where and the set, {, 2,3, ), is referred to as the generalized Fourier Series 3. Without using Matlab, derive an expression for the exponential Fourier series for the follow- ing signals: ft)-(-1 1 0St
