The solve function returns a structure when you specify a single output argument and multiple outputs exist. 6 of them are non-linear and 4 of then are linear . Learn more about solve for variable For example if you havetwo non-linear equations in two varaibles 'x' and 'y', you should write them as x(1) and x(2) , this can be extended to the number of variables you need to solve. Based on your location, we recommend that you select: . Solving a system of equations with two unknowns is a very easy cake to bite but when the number of unknown exceed two, solving the system of equations becomes complicated and time-consuming. It is, maybe, the most used operation in science and engineering, too. Solving a set of equations in linear algebra on a computer is nowadays as basic as doing arithmetic additions using a calculator. This is just an overview of the techniques; MATLAB provides a rich set of functions to work with differential equations.
