solb = solve (eqn, b) solb = - (a*x^2 + c)/x If you do not specify a variable, solve uses symvar to select the variable to solve for. For example, solve (eqn) solves eqn for x. Return the Full Solution to an Equation solve does not automatically return all solutions of an equation. Solve the equation cos (x) == -sin (x) .

Solving Basic Algebraic Equations in MATLAB 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 −

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.

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 ...

For analytic solutions, use solve , and for numerical solutions, use vpasolve . For solving linear equations, use linsolve . These solver functions have the ...

Solve the equation using dsolve. ySol (t) = dsolve (ode) ySol (t) = C1*exp (t^2/2) Solve Differential Equation with Condition In the previous solution, the constant C1 appears because no condition was specified. Solve the equation with the initial condition y (0) == 2. The dsolve function finds a value of C1 that satisfies the condition.

Equations and systems solver - MATLAB solve - MathWorks France solve Equations and systems solver collapse all in page Support for character vector or string inputs has been removed. Instead, use syms to declare variables and replace inputs such as solve ('2*x == 1','x') with solve (2*x == 1,x). Syntax S = solve (eqn,var)
