need some help in Matlab coding

s2(t) A2.1 Generate and plot a periodic signal based on s2(t) named s2 hinf The signal is to span 5 cycles (periods) and have a total of 500 sample points (i.e. 100 points per period) A2.2 Compute the trigonometric coefficients of s2(t), numerically using MATLAB. Do not use the trapz or syms functions. A2.3 a 4x500 matrix called s2 matrix. The first row represents the DC component of s2(t) Each remaining row contains a single harmonic component of the signal for n E 0,1,2,3) can use s2 matrix to do this. series approximations using the trigonometric coefficients: A2.4 Now create a vector s2 approx which contains an approximation of the signal s2(t). You A2.5 In the same figure as s2.hinf, and using different colours, also plot the following Fourier Hint: this can be implemented in a for loop An approximation of s2(t) using the DC component and the fundamental frequency, An approximation of s2(t) using the DC component, the fundamental frequency and the second harmonic, An approximation of s2(t) using the DC component, the fundamental frequency and the second and third harmonics. Note that the fundamental, second harmonic and third harmonic correspond to n 1,2,3 respectively s2(t) A2.1 Generate and plot a periodic signal based on s2(t) named s2 hinf The signal is to span 5 cycles (periods) and have a total of 500 sample points (i.e. 100 points per period) A2.2 Compute the trigonometric coefficients of s2(t), numerically using MATLAB.
