Variables for which you solve an equation or system of equations, specified as a symbolic vector or symbolic matrix. By default, solve uses the variables determined by symvar . The order in …

Solve an Equation. If eqn is an equation, solve(eqn, x) solves eqn for the symbolic variable x. Use the == operator to specify the familiar quadratic equation and solve it using solve.

Jan 21, 2016 · I just meant that... can I use matlab to solve for a certain variable in any complex equation in the mould of z(x,y) = x + y + many constants,variables,etc.

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]);

This MATLAB function numerically solves the equation eqn for the variable var using variable-precision arithmetic and returns the solutions with 32 significant digits by default.

Feb 6, 2018 · I have 5 values for x (x = 0, 15, 30, 55, and 85) and an equation with cos, say cos(x), and I need to find the answer for each of these values. Is there any way to do this while …

Solve a quadratic equation without specifying which variable to solve for. The solve function chooses x to return a solution. >> syms a b c x >> eqn = a*x^2 + b*x + c == 0 >> S = …

Solve differential algebraic equations (DAEs) by first reducing their differential index to 1 or 0 using Symbolic Math Toolbox™ functions, and then using MATLAB ® solvers, such as ode15i, …

This example shows how to solve two nonlinear equations in two variables. The equations are e - e - ( x 1 + x 2 ) = x 2 ( 1 + x 1 2 ) x 1 cos ( x 2 ) + x 2 sin ( x 1 ) = 1 2 .

Numerically solve equations to arbitrarily high precision, use search ranges, and visualize results.
