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.

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 −

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.

Solve Robertson Problem as Semi-Explicit Differential Algebraic Equations (DAEs) Open Script. This example reformulates a system of ODEs as a system of differential algebraic equations (DAEs). The Robertson problem found in hb1ode.m is a classic test problem for programs that solve stiff ODEs. The system of equations is.

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) .

Solve System of Algebraic Equations This topic shows you how to solve a system of equations symbolically using Symbolic Math Toolbox™. This toolbox offers both numeric and symbolic equation solvers. For a comparison of numeric and symbolic solvers, see Select Numeric or Symbolic Solver. Handle the Output of solve Suppose you have the system

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

There are several ways to address the output of solve. One way is to use a two-output call. The call returns the following. [solx,soly] = solve (x^2*y^2 == 0, x-y/2 == a) solx =. soly =. Modify the first equation to . The new system has more solutions. Four distinct solutions are produced.

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.
