matrices: using the numpy() library, we can define a matrix as a array of arrays of rows; we can do arithmetic, apply operators and numpy() functions, and compute statistics. We can create a magic matrix; we can create a 2D grid for plotting or approximation. we can plot selected rows of a matrix, or the entire set of data.

Lecture notes:

• matrices.pdf

• magic_matrix.py, the magic matrix (odd order only).

• meshgrid_example.py, create a 2D grid.
• meshgrid_example.png, a contour plot created over a 2D grid.

• temperature.py, work with a matrix of temperature measurements. Plot each day's results, then the whole set of data. Compute daily, hourly, and total minimums.
• temperature_daily.png, a plot of each day's temperature data.
• temperature_week.png, a plot of the entire set of data.
