What is MATLAB?
▪ High-level computer language designed for
scientists and engineers.
▪ Combination of an easy-to-use, interactive
desktop environment with matrix-based
language.
▪ Extendable using toolboxes that provide
targeted functionality for specific types of
analysis or area of expertise.

Example: Bicycle Traffic Analysis
▪ Bicycle count for journeys toward
Harvard (Westbound) and toward
City Centre (Eastbound).
▪ Counts recorded every 15 minutes
▪ Data contains:
– Timestamp
– Day of the week
– Counts separated by journey direction
– Total bicycle counts per 15 minutes

Compare with Weather Data
▪ Historical weather data for Boston, MA.
▪ Same time period as bicycle traffic data.
▪ We have data for:
– Average wind speed (MPH)
– Precipitation (inches per day)
– Average daily temperature (ºF)
– Maximum daily temperature (ºF)
– Minimum daily temperature (ºF)
