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

Solve Algebraic Equation. Symbolic Math Toolbox™ offers both symbolic and numeric equation solvers. This topic shows you how to solve an equation symbolically using the symbolic solver solve.To compare symbolic and numeric solvers, see …

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.

If solve cannot find a solution and ReturnConditions is false, the solve function internally calls the numeric solver vpasolve that tries to find a numeric solution. For polynomial equations and systems without symbolic parameters, the numeric solver returns all solutions.

If solve cannot find a solution and ReturnConditions is false, the solve function internally calls the numeric solver vpasolve that tries to find a numeric solution. For polynomial equations and systems without symbolic parameters, the numeric solver returns all solutions.

Symbolic Math Toolbox provides a set of functions for solving, plotting, and manipulating symbolic math equations. You can generate MATLAB functions, ...

System of equations or expressions to be solve, specified as a symbolic vector, matrix, or array of equations or expressions. These equations or expressions can also be separated by commas. If an equation is a symbolic expression (without the right side), the solver assumes that the right side of the equation is 0.

You can solve equations to obtain a symbolic or numeric answer. For example, a solution to cos ( x ) = − ...

Solving ODE Symbolically in MATLAB First Order Equations We can solve ordinary differential equations symbolically in MATLAB with the built-in M-file dsolve. Example 1. Find a general solution for the first order differential equation y′(x) = xy. (1) We can accomplish this in MATLAB with the following single command, given along with

S = vpasolve( eqn , var ) numerically solves the equation eqn for the ...

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.
