If vpasolve cannot find a solution, it returns an empty object. Provide initial guess to help the solver finding a solution. For an example, see Provide Initial Guess to Find Solutions.. For polynomial equations, vpasolve returns all solutions. For nonpolynomial equations, there is no general method of finding all solutions and vpasolve returns only one solution by default.

Prerequisites

The solve function returns a structure when you specify a single output argument and multiple outputs exist. Solve a system of equations to return the solutions in a structure array. syms u v eqns = [2*u + v == 0, u - v == 1]; S = solve (eqns, [u v]) S = struct with fields: u: 1/3 v: -2/3.

syms x a eqn = x^3 + x^2 + a == 0; solve (eqn, x) ans =. Try to get an explicit solution for such equations by calling the solver with 'MaxDegree'. The option specifies the maximum degree of polynomials for which the solver tries to return explicit solutions. The default value is 2.

Copy to Clipboard. function b = Solution (a,b)%a and b must bound the solution (a=5.2, b=5.3) f=@ (x)x^4+x-750; while f (b)>.000001%whatever accuracy you want here.

The solve function is used for solving algebraic equations. In its simplest form, the solve function takes the equation enclosed in quotes as an argument. For example, let us solve for x in the equation x-5 = 0. solve ('x-5=0') MATLAB will execute the above statement and return the following result −. ans = 5.

Solve a system of equations to return solutions in a structure array >> eqns = [2*u + v == 0, u - v == 1]; >> S = solve (eqns, [u v]) S = struct with fields: u: 1/3 v: -2/3. Access the solutions by addressing the elements of the structure. Using a structure array allows you to conveniently substitute solutions into other expressions.

S = solve( eqn , var ) solves the equation eqn for the variable var . If you do not specify var , the symvar function determines the variable to solve for.
