Maple Labs

Extra package - vec_calc

Before doing any lab, you should make sure that your Maple is upgraded with an additional software package called vec_calc. You will not be able to complete your lab assignments without this extra package.

To make sure that your vec_calc package is installed, try to perform the following command at the Maple prompt:

> with(vec_calc);

If you got some blue output with a long list of names separated by commas - everything is OK. If you got a purple message saying the the package does not exist - then the vec_calc package has not been installed, you have to fix the problem.

Dowloading and saving files

For each lab, except the very first one, you will need 2 files: the worksheet file that you are supposed to read through, try the commands and understand the material, and the assignment file containing exercises that you are supposed to complete, print out (together with the output) and turn in to obtain the credit.

To download a file from a web browser, click on the file name with your right mouse button and do "Save Link" or "Save Target". Remember the directory on your local computer where you saved the files. Then, bring up the "Maple" from your desktop or by clicking on any .mws file icon. Within "Maple", open the file(s) you have just saved.

If you have no time to finish the exercise during one session, you may save your half-finished work on your local computer -- try to make a unique name for it, so that the file would not be accidentally erased or overwritten by other students. Still this is not 100% safe. A better solution is to always have with you a floppy disc and save your half-finished work on the floppy. Alternatively, you may save it on on your computer account via FTP.

Another important notice!
Before saving a file on a diskette or sending it via FTP or email, remove all the output by clicking on "Edit" then pointing on "Remove output" then on "From worksheet". This way, you will not lose any of your work but the file will become considerably smaller. A file with output may be so large that it will not fit on a diskette. In this case, an attempt to save it may destroy the file! You may restore your output later, by repeatedly pressing "Enter". Don't forget to restore all the output before printing the file out.

Important!!! Every worksheet file should begin with four commands: restart; with(vec_calc); with(linalg); with(plots); The first command clears the memory. The other three commands allow access to the vec_calc package and other necessary packages.
