5. MATLAB 1: Modify the code given in MATLAB 1.4 (ML0104 on p.24) to generate a plot where the amplitude is 4 V/m, the wave is attenuated by an attenuation of 0.001 Np/m, at the frequency of 1 MHz. In your summary statement, convert your attenuation factor from Np/m to dB/m. Paste your MATLAB code, plot, and a short summary statement into a single pdf document and upload to the Canvas website under MATLAB Assignments by the due date. 8 8 8 M-File: ML0104 Program plots wave (in vacuum) versus z-position for a fixed time.

Write MATLAB code that will plot the function x² - 10x + 25 over the x values 0 to 10 on a regular plot (use the command plot) using 21 evenly spaced points with the linspace command in one subplot and then for the second subplot, plot the same function over the x values 10-¹ to 10 ¹ using 21 evenly spaced points on a semi logarithmic plot (use the command semilogx). Put markers on each point used in the calculations (using a circle, x, or +, your choice) using a different marker and color for each plot, and include axis labels on each subplot. If the code is written correctly, your subplots should appear like the ones below. 25 y-axis 20 15 10 X 5 0 0 2 4 x-axis 6 8 10 25 PO 20 y-axis 15 10 5 0 10-1 O Copy/paste your code that will create the subplots in the text box below. 0 0 0 0 0 0 0 10⁰ x-axis 0 0 0 0 0 10¹

In MATLAB:  Write a program to plot an image and it's histogram. Take the address of image as: xyz.jpg  Please attach a correct code so that I can run it with my image on my system.
