Please attach all code that you use. Attach code at end of submission. In general try to keep your answers concise. Use as many words as you need and no more. Also work on your presentation skills. This means organize your plots and displays. Always use titles and add captions when appropriate. Points will be awarded for clarity and presentation. Written exercises 1.

Matlab exercises 1. Working with Plots and images in Matlab. (a) Download Figure 1.14(c) from the textbook photo gallery. In Matlab, use imread to load in the image, and convert the image from uint8 to double by typing I=double(I); . (b) Read the help files for the following commands: plot , fplot , subplot , hold , stem , title , text , gtext , getrect , ginput , image , imagesc , truesize , pixval , imcrop , colormap , colorbar . You will be using these functions often so get to know them well.
