WebJun 7, 2013 · The set of initial conditions Y0 is a matrix with a number of rows equal to the size of the problem Yet, you specify x0 = [0 pi/2]; This has two columns. If you change it to two rows: x0 = [0; pi/2]; It will work. (I just tried with your example).

Pass an empty matrix for optionsto use the default values for options. [x,fval] = fsolve(fun,x0) returns the value of the objective function funat the solution x.
