I need help in MATLAB HW

1. (1) In one figure window and without using subplot plot y=mx+b with m = 2, b = � 0, 1 from c = 0.01 ? 100 using: a) plot(x, y); grid b) semilogx(x, y); grid c) semilogy(x, y); grid d) loglog(x, y); grid So four plots, each with three curves. Comment on the results (2) What functions produce straight lines when plotted using semilogx and semilogy? Show example plots 2. Write a script that makes a line plot of sinc function y(x)=sinc?(px)=sin?(px)/px from x = � to 10. Use eps to address the singularity that occurs at x = 0. Use handle graphs make the figure fill a 5 inch wide by 2 inch tall. The curve should be a thick purple line. 3. Make a polar plot of the following function: y(x)=sin?(2x) Use handle graphs make the figure fill a 5 inch by 5 inch square. The curve should be a thick green dash line. 4. Use the MATLAB� audio command to create a sound file (.wav) using 22,000 random numbers and a sampling frequency of 44 kHz. What is the duration of this sound clip? 5. Import and plot federal_funds_rate.xlsx since 1955. Also save a plot in either .png or .jpeg format. 6. Use a single fimplicit function to plot the following hyperbolars in one plot. y^2-x^2=c for c = � � 0, 2, 4 7. The command spiral(3) generates the following number spiral matrix S3 = (7 8 9 6 1 2 5 4 3) where it starts with the number 1 at the center of the matrix and counts up by spiraling around the center. (a) Write a program that makes a 2-D plot binary that differentiates the prime numbers from the non-prime numbers in this matrix for a relatively large spiral matrix, say n > 250. (b) What percentage of the values in the matrix are prime numbers? (c) In the same plot window, make a second plot of a 2-D matrix of randomly distributed ones and zeros that has the same percentage of ones as the first matrix. (d) Comment on the differences you see in these plots
