[sympy] maximize with constraints

2009-02-18 Thread flyeng4
I am trying to use sympy to solve a couple optimal control problems with the Pontryagin Maximum Principle. Right now I am trying to solve a single problem in an ad hoc fashion and then I will hopefully be able to add some generality to this. To get started I need help with solving an equation su

Hi Ondrej You are so thoughtfull that I'm heartwarming. -- I am an engineer and using scipy, sympy and my python libraries. They are more usefull for me than Matlab, Mathematica, Maple etc. Because I try and test some calculations/expresions along studying

All, To introduce myself, I am in my second semester of grad school at Southern Illinois University Edwardsville. I use python for pretty much everything I do programming wise but I am far from knowledgeable (about a year experience). I really enjoy programming and I try to make an excuse to co

[sympy] Set Algebra module.

2009-02-18 Thread Akshay Srinivasan
Hello, I'm trying to implement a Set Algebra module for sympy. I started coding a few days ago and it quickly became apparent that I have to write something completely parallel to the normal algebra, which is already present in Sympy. I've written a very rough code, which contains some clas

[sympy] Differential Equations with Initial Conditions

2009-02-18 Thread Alex_Gaynor
A common task with differential equations is to solve them given some initial condition. In sympy this can be done manually by substituting in for x and then solving for C1(and possibly solving the system if you have C2), it would be nice it dsolve() could handle this automatically similarly to h
