Phase Portraits - pplane6 The routine pplane6 is already loaded on all PUCC machines as standard software. If you are using your own copy of Matlab you may need to download pplane6 .Hereisal ink: http://math.rice.edu/ dfield/ (Note: pplane5 is an older version of pplane6 .) To access pplane6 ,ata Matlab prompt type: pplane6 A popup window will appear (similar to that for dfield6 ). Correctly enter your system of differential equations and the range of values of the indepen- dent and dependent variables. Hit Proceed and a graphics window will appear with the

Unformatted text preview: corresponding trajectory through that point will be plotted. • There are several options available in the graphics display window : printing, keyboard input of initial conditions, inserting text, erasing solutions, zoom, etc. • You may have up to four parameters to quickly vary your differential equations (rather than having to retype the same differential equations with different constants). • pplane6 is very similar to dfield6 in its syntax and use....
