# UBC Math 255 for Mech 2, Sep-Dec 2014

This page provides unofficial backup for the materials that students can and should find on UBC's Connect e-learning system.

In cases of dire need (e.g., server failure), these unofficial copies should be better than no access at all.

## Computer Lab 7: Numerics and Neurons

There is no official prelab assignment. However, carefully reading the lab specifications and the provided helper scripts before the lab period will turn out to be time well spent.

## Computer Lab 6: The Simple Pendulum

There is no official prelab assignment. However, carefully reading the lab specifications and the provided helper scripts before the lab period will turn out to be time well spent.

## Computer Lab 4: Solving a Separable ODE

Please note that the prelab requires some work to be completed before the lab starts, and handed in at the beginning of your scheduled session.

## Computer Lab 1: Histogram

• Lab Activities (PDF)
• smallMONtest.mat -- small test data set for Monday
• bigMONtest.mat -- big test data set for Monday
• smallTUEtest.mat -- small test data set for Tuesday
• bigTUEtest.mat -- big test data set for Tuesday
• smallWEDtest.mat -- small test data set for Wednesday
• bigWEDtest.mat -- big test data set for Wednesday
• smallFRItest.mat -- small test data set for Friday
• bigFRItest.mat -- big test data set for Friday.
Special note for Friday: To make the big test data set look most excellent, modify your 'hyst' function so that it shows each bar in the histogram as a filled black rectangle. If you follow the lab instructions, you probably make each bar by issuing a command something like "plot(x-value-list,y-value-list)", with the lists adapted to the bins and counts in each subinterval. To get solid black bars instead, just change the command "plot" to "fill" and add a one-character colour specification. The character for black is 'k', so you want to replace that one line with "fill(x-value-list,y-value-list,'k')". Note the single-quotes around the character 'k': those are required.
