# Thread: Solving/Roots of nonlinear System of Equations - Java - Android

1. ## Solving/Roots of nonlinear System of Equations - Java - Android

I was hoping that someone might be able to help me with this problem because I have spent about a week without success. I am in search of a library that has been created in JAVA that can be utilized to solve for roots of a nonlinear system of equations. Each equation has 2 variables, x and y, and will need a library that uses higher calculus equations. No ones that just solve for x.

Most of the libraries that have been created to solve nonlinear equations are either in Fortran, C, or Python. There are a few libraries such minpack/scipy. The only libraries that I have been able to find or programming solutions that are in JAVA either require additional programs such as Matlab or are commercial products

I did find one library put together by a professor in Colorado State, but am unsure how to use it. There does not seem to be a way to enter your functions in the code.

Newton Raphson Method - Multivariable(x and y)

If someone can figure out how to use this library or find a library that can be used in an android application would be amazing. Let me know if you have questions!

Thank you for the help!
