Homework guidelines

Due dates/late policy

Homeworks will only be accepted electronically through the EEE dropbox. The dropbox will have a automatic deadline of 11:59 pm on the given due date. No homeworks will be accepted after that time. I know this is a tough requirement, but in return, I'll award extra credit for early-submitted homeworks as described below. If you are working down to the last minute, please make sure something is uploaded 10 minutes prior to the deadline to ensure you won't get zero credit.

Grading

Each assignment has both programming and written components. Your code will be graded both on clarity and correctness. It is generally more important that your code be clear and correct than fast. Your writeup should be richly illustrated with graphs and images, and your code should be well commented and documented.

Extra-credit

Any homework that is handed in one day early (11:59 pm on the previous day) will get 5% extra-credit. For a 100-point assignemnt, this is 5 extra points.

Homework Submission Instructions

Submit a pdf file with your writeup into the appropriate directory in the EEE Dropbox. Also submit a zip archive containing all your code. If I hand out code as part of the assignment, please include that also.

Zip of the files titled firstname_lastname.zip You can create the zip file ways depending on the platform:

Select the set of files and right-click, select "Create archive". Select either "zip" to create the archive, or
In a terminal, cd to the directory containing your code and type zip *.m firstname_lastname.zip to create the zip file.

You can list the contents of a zip archive with the command unzip -l firstname_lastnape.zip

Homework Writeup Guidelines

You must submit your writeups as as a single PDF file. I will not accept writeups in any word processing format such as MS Word or Open Office. You are welcome to create the writeup in whichever word processor you like but in the end you need to save it as a pdf file.

Some guidelines for your figures:

Use a proper size and aspect ratio. If you are showing an image, make sure that the pixels are displayed square. Use the axis image command. If the image is not too large, ensure that image and screen pixels coincide with the truesize command.
Always show the colorbar for 2D data. Whether your are showing an image or data in the form of an image, always show the colorbar. If you are showing an image, this will verify that the color map spans the correct range (usually [0,1]). If you are showing data, then this will show the meaning of the colors. The only exception is when you show RGB images; in that case, the colorbar is meaningless because the colormap is not used.
Use a sensible color map. There are a couple standard color maps available in MATLAB: gray, jet, and hsv. In the few cases where your data is periodic (such as with angles), then use colormap hsv. Otherwise, use gray or jet. Which is appropriate depends on what you are trying to show. Use the colormap that most effectively communicates your point.
Use a proper display range. If you are showing a grayscale image, make sure that MATLAB does not remap the colors. The imagesc command has an optional parameter for this purpose, e.g. imagesc(im,[0,1]) will make sure the color map spans the range [0,1]. If you are showing data, then allowing imagesc to scale the color map to the range of the data is usually appropriate. If your data is mostly symmetric around zero, then consider using a display range that is symmetric around zero, e.g. imagesc(im,[-1,1]*max(abs(im(:))))
Consider screen capture for figures. There are three ways to create images of your figures in MATLAB:
- Use a screen capture utility.
- Select File > Save As... from the figure window, and export as an image (PNG, TIFF, JPG, etc.).
- Use the print command.
Use imwrite() for saving images. To directly export an image from Matlab, use the imwrite command.
