8. Matlab Lecture 8

This lecture focuses on data acquisition, manipulation, plotting, and meshing. The following files can be used for examples:

Raw Data and Matlab m-files for data preparation:

gas_all_grades.csv   Data: Gasoline prices for different regions over various time periods.

geography.csv   Data: description of regions and codes.

plot_gasprice1.m   M-File script for data preparation and plotting (1)

plot_gasprice2.m   M-File script for data preparation and plotting (2)

indexOf.m   Function for data preparation

extractRegion.m   Function for data preparation

Cleaned-up data:

cities.csv   Data: Selected U.S. cities

states.csv   Data: Selected U.S. states

regions.csv   Data: U.S. regions

Additional m-files:

xticklabel_rotate.m   M-File used for rotating labels on the x-axis
