Homework and assignments

HW2: Hand calculation worksheet - array manipulation (4 points)

Complete the array manipulation practice sheet and bring the completed sheet to class on the due date. The assignment will be collected at the beginning of class, graded, and returned to you during a subsequent class for discussion. (See the course Blackboard calendar for the due date.) You can download extra copies of the practice sheet at http://www.cs.utsa.edu/~cs1173/resources/CS1173HandCalculationWorksheetHW2.pdf

HW3: Hand calculation worksheet - bars and pies (4 points)

Complete the array manipulation practice sheet and turn it in during class. The assignment will be collected at the beginning of class, graded, and returned to you during a subsequent class for discussion. (See the course Blackboard calendar for the due date.)You can download extra copies of the practice sheet at http://www.cs.utsa.edu/~cs1173/resources/CS1173HandCalculationWorksheetHW3.pdf

HW4: Three-week sleep diary (10 points)

Keep a sleep diary for 3 weeks starting Wednesday, February 8, 2012 and ending Tuesday, February 28, 2012. THIS IS A MAJOR ASSIGNMENT. You will not be able to do some of the later course projects and assignments without this diary. The data from your diary will be pooled with that of the other students (after it is anonymized). You will be doing some analysis of the entire collection, as well as a comparison of how your sleep patterns compare with those of the rest of the cohort.

Keep your diary both on the hard copy log sheet ( http://www.cs.utsa.edu/~cs1173/resources/CS1173SleepDiaryLogSheet.pdf) and in the sleep diary Excel spreadsheet http://www.cs.utsa.edu/~cs1173/resources/CS1173SleepDiarySpreadsheet.xlsx. Just before uploading, save your spreadsheet in comma-separated-value format with the file name LAST_FIRST_GENDER.csv. For example, John Doe would save his file as Doe_John_male.csv. Note: Your hard copy diary will be collected in class Wednesday, Feb 29 or Thursday, Mar 1.

Additional handin instructions (we will go through the handin process in class):

• Download ../downloads/SleepDiarySpring2012.zip and unzip it into your MATLAB directory on your Z: drive. This folder contains the MATLAB scripts you will need to process your sleep diary.
• Download the http://www.cs.utsa.edu/~cs1173/resources/CS1173SleepDiarySpreadsheet.xlsx spreadsheet and enter your sleep diary data.
• Be sure that you have correctly entered your sleep diary data into the Excel spreadsheet. Save the spreadsheet as a comma separated value (.csv) file. Note: it is not enough to change the file name. You also have to change the Save type as. Save your comma-separated value file in the SleepDiaryProcessing directory that you just unzipped. Use a filename that contains your name in it.
• Open MATLAB and edit the testScript so that it contains your specific information (the .csv file name, your last name, your first name, your gender, and your section number.)
• Run testScript. If the script runs successfully, you should see a .mat file to hand-in. If the script throws an error, you will need to correct your .csv file and run again.
• Hand-in both the .csv file and your .mat file by uploading to Blackboard under Homework Assignment 4 (HW4).
• You will hand in your hard-copy in class.

HW5: Hand calculation worksheet - vector indexing (4 points)

Complete the vector indexing practice sheet and bring the completed sheet to class on the due date for check-off and discussion. You can download extra copies of the practice sheet at http://www.cs.utsa.edu/~cs1173/resources/VectorIndexingWorksheetHW5.pdf
