Hi,
Sympy seems is rather advanced and useful project. I've tried to test it using jhepwork, and even included it into http://jwork.org/jhepwork/download/ (version 2.0) for test purpose (directory python/packages) Apparently, one can run sympy using Jython (v2.5) and Java ! A code snipped is below. Load it into the jHepWork IDE editor and press the button [run]. However, there is on feature I want to understand. To plot a function as in the example below using F1D class, I need to pass a string representing this function. However, simpy cannot accept strings for the statements such as diff() or integral(). In the below example, what I want to do is to type "diff(func,x)". Further, if I want to plot the result of "diff" or integration, I need again a string representing the output function and pass it to the F1D class as in the example. How can I do this? thanks, Sergei ******************************************************** # jHepWork Jython example from java.awt import Font,Color from jhplot import * c1 = HPlot("Canvas") c1.setAutoRange() c1.setGTitle("Example", Color.red) c1.setNameX("X") c1.setNameY("Y") c1.setName("Simpy example") c1.visible() c1.setAutoRange() # draw function func="2*exp(-x*x/50)+sin(pi*x)/x" f1 = F1D(func, -2.0, 5.0) c1.draw(f1) # use sympy from sympy import * x = Symbol('x') print diff(2*exp(-x*x/50)+sin(pi*x)/x, x) # how to get string with the result # to build F1D with results for drawing? # export to some image (png,eps,pdf,jpeg...) # c1.export(Editor.DocMasterName()+".png") --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
