Solve systems of nonlinear equations in serial or parallel Find a solution to a multivariable nonlinear equation F ( x) = 0. You can also solve a scalar equation or linear system of equations, or a system represented by F ( x) = G ( x) in the problem-based approach (equivalent to F ( x) – G ( x) = 0 in the solver-based approach).

06.04.2012 · How can i solve a system of nonlinear differential equations using Matlab?? here is an example of what i'm talking about it's not the problem that i'm working in but it had the same form. //// x'=3x+y//// y'=y-x+y^4+z^4//// z'=y+z^4+y^4+3/// the ' means the derivative. i'll appreciate your help, best regards!
Solve nonlinear minimization and semi-infinite programming problems in serial or parallel using the solver-based approach. Before you begin to solve an optimization problem, you must choose the appropriate approach: problem-based or solver-based. For details, see First Choose Problem-Based or Solver-Based Approach.
