6. 6 Computing Software Matlab: a programming language for matrix-vector operations, with good graphics and visualization capabilities Maple: a programming language for symbolic computation Mathematica: not licensed by SOE

7. 7 Examples of Matlab http://www.soe.ucsc.edu/~hongwang/Codes/Plot_1D_2D/ Plotting curves and surfaces http://www.soe.ucsc.edu/~hongwang/Codes/Read_data/ Run “plot_fx.m” to see how to plot curves. Run “plot_fxy.m” to see how to plot a surface. Run “plot_Cities_pop.m” to see how to read in data, plot populations of 6 cities vs time, and use legend to label curves. http://www.mathworks.com/access/helpdesk/ Online Matlab manuals

8. 8 Examples of Matlab (continued) Visualization of motion GUI (Graphical User Interface) http://www.soe.ucsc.edu/~hongwang/Codes/Two_body/ http://www.soe.ucsc.edu/~hongwang/AMS27/Lab/illustration_4.html http://www.soe.ucsc.edu/~hongwang/Codes/Image_compression/ First run “calc_2body.m” to generate the numerical solution. Then run “visualize_1.m” to visualize the motion. Run “ODE_4.m” to use the GUI. Run “demo_color.m” and / or run “demo_grayscale.m” to see the effect of image compression.

9. 9 More Programming Languages http://www.soe.ucsc.edu/~draper/ HTML (Hyper Text Markup Language): -- learn it by reading other webpages R: -- Professor Kottas will talk about it Example: Professor Draper’s webpage IDL (Interactive Data Language): -- you will learn it later from Professors Brummell and Garaud if …
