Solve the equation cos (x) == -sin (x) . The solve function returns one of many solutions. syms x solx = solve (cos (x) == -sin (x), x) solx = -pi/4. To return all solutions along with the parameters in the solution and the conditions on the solution, set the ReturnConditions option to true. Solve the same equation for the full solution.
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.

Solve the system of equations using solve . The inputs to solve are a vector of equations, and a vector of variables to solve the equations for. sol = solve ( [eqn1, eqn2, eqn3], [x, y, z]); xSol = sol.x ySol = sol.y zSol = sol.z. xSol = 3 ySol = 1 zSol = -5. solve returns the solutions in a structure array.
This MATLAB function numerically solves the equation eqn for the variable var. ... To find more than one solution for nonpolynomial equations, set 'Random' to true. ... Equation to solve, specified as a symbolic equation or symbolic expression.
2 x 1 - x 2 - e - x 1 = 0 - x 1 + 2 x 2 - e - x 2 = 0. Start your search for a solution at x0 = [-5 -5]. First, write a function that computes F, the values of the equations at x. F = @ (x) [2*x (1) - x (2) - exp (-x (1)); -x (1) + 2*x (2) - exp (-x (2))]; Create the initial point x0. x0 = [-5;-5];
06.02.2018 · Use a vector. x = [0, 15, 30, 55, 85]; y = cosd (x) y =. 1 0.96593 0.86603 0.57358 0.087156. Note the use of cosd, since x is clearly in degrees. The learning point is that MATLAB is a matrix language (vectors too.) Most such functions are vectorized, so that you can pass in a vector or array of values.
For polynomial equations, vpasolve returns all solutions. syms x S = vpasolve (2*x^4 + 3*x^3 - 4*x^2 - 3*x + 2 == 0, x) S =. Solve a nonpolynomial equation. For nonpolynomial equations, vpasolve returns the first solution that it finds. S = vpasolve (sin (x) == 1/2, x) S =.
