MATLAB PROJECTS:

Read the instruction in the file, and then do the problems. Those problems with a ‘star’ should be explained by words, based on the MATLAB output. After you have done all the problems in a script file ‘filename.m’, type the command publish(‘filename.m’,’pdf’) to create a PDF file. Submit the PDF file to ELMS.

Here is a sample of what the script file and the PDF file should look like:
