1. Graphs in MATLAB Christian Ruff

2. Why use MATLAB to create graphs? One single programme to process data and plot results: –Transfer errors are less likely –Every step of analysis and plotting is well documented One button click can re-create the final graphs if the data change Graphs can be (re-)created in every image format and print resolution MATLAB is **much** more flexible than SPSS or EXCEL May not seem as intuitive to use as SPSS or EXCEL, but you can always check out help, doc, and the excellent manuals online

3. Graphs in MATLAB: extensions and help The add-on image processing toolbox contains functions for many advanced image analyses and transformations Other graphing (helper) functions and can be found on WWW: –http://www.mathworks.com/matlabcentral/fileexchangehttp://www.mathworks.com/matlabcentral/fileexchange –See e.g., http://www.mathworks.com/company/newsletters/digest/june00/export/ http://www.mathworks.com/company/newsletters/digest/june00/export/ If you want to know which types of graphs are possible, look at the excellent MATLAB documentation at: –http://www.mathworks.com/access/helpdesk/help/techdoc/http://www.mathworks.com/access/helpdesk/help/techdoc/

6. How does MATLAB “think about” graphs? Figures contain axes contain objects We can access figures, axes, and objects via their handles Figures, axes, and objects have properties, which we see by get and change by set All of these operations can also be performed by mouseclick!
