An equation or a system of equations can have multiple solutions. To find these solutions numerically, use the function vpasolve . For polynomial equations, ...

Solve differential algebraic equations (DAEs) by first reducing their differential index to 1 or 0 using Symbolic Math Toolbox™ functions, and then using ...

A == B defines a symbolic equation. Use the equation as input to functions such as solve , assume , fcontour , and subs .

Then you can solve the equation by calling the solve function. For example, solve ...

For in-depth information on solving symbolic equations including differential equations, see Equation Solving. Solve Algebraic Equations with One Symbolic Variable. Use the double equal sign (==) to define an equation. Then you can solve the equation by calling the solve function. For example, solve this equation:

Solve the quadratic equation using the solve function. Solve the quadratic equation without specifying a variable to solve for. The solve function chooses x to ...

Solve an Equation · syms a b c x eqn = a*x^2 + b*x + c == 0; solx = solve(eqn, x).

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.

Numerically Solve Equations. When the solve function cannot symbolically solve an equation, it tries to find a numeric solution using the vpasolve function. The vpasolve function returns the first solution found. Try solving the following equation. The solve function returns a numeric solution because it cannot find a symbolic solution.

Equation to solve, specified as a symbolic expression or symbolic equation. The relation operator == defines symbolic equations. If eqn is a symbolic expression ...

f( inputs ) = formula creates the symbolic function f . For example, f(x,y) = x + y . The symbolic variables in inputs are the input arguments.

You can differentiate symbolic functions, integrate or simplify them, substitute their arguments with values, and perform other mathematical operations. For example, find the derivative of f (x,y) with respect to x. The result dfx is also a symbolic function. dfx = diff (f,x) dfx (x,y) = 2*x*y. Calculate df (x,y) at x = y + 1.
