The solution to the problem has 4 solutions, roots of a 4th order polynomial equation, here in the variable z. MATLAB can solve for those roots numerically.

Jun 25, 2015 · i'm trying to use 'solve' method to solve equations in matlab , i have a matrix which Coefficients of the variables are in it called 'A' but when i use solve method with this code (i want A(1,1) to be the Coefficients for x variable) :

Oct 20, 2021 · The solver returns a set of this type if it cannot solve an equation explicitly in terms of radicals. The solver also can return this type of set when you use the MaxDegree option. This is not the same as roots (), in that roots () is purely for numeric coefficients and roots () find numeric approximations.

In Matlab, fsolve is the function that is used to solve nonlinear equations. It solves the equations and returns a vector value for the objective function entered in the syntax. Working of fsolve in Matlab with Syntax and Examples

Y = solve (eqns,vars) solves the system of equations eqns for the variables vars and returns a structure that contains the solutions. If you do not specify vars, solve uses symvar to find the variables to solve for. In this case, the number of variables that symvar finds is equal to the number of equations eqns. example

29.04.2014 · I have a pretty large equation in which I need to solve for a ratio of 2 variables/symbols. A small example would be: Y = A*Y + B*X and I want MATLAB to solve this as Y/X = B/(1-A) where the an...

Y = solve (eqns,vars) solves the system of equations eqns for the variables vars and returns a structure that contains the solutions. If you do not specify vars, solve uses symvar to find the variables to solve for. In this case, the number of variables that symvar finds is equal to the number of equations eqns. example

Sep 24, 2016 · Accepted Answer: Star Strider. When using the solve command with a variable included, it always returns an equation in terms of a variable. Is there any way to get it to return the actual value? An example would be. asdf = 2.5. jkl = solve ('2*asdf = x', 'x') which returns.

13.01.2013 · However your sixth equation 2*V33=0 renders the following equation -2*D*V33=0 redundant...so you actually only have eight independent equations, hence the extra parameter z. I don't know more about the details about your PDE to tell you why it isn't well-posed, but basically you need another equation involving your nonzero variables if you expect a unique solution.

When solving for multiple variables, it can be more convenient to store the outputs in a structure array than in separate variables. The solve function returns ...

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. …

S = solve( eqn , var ) solves the equation eqn for the variable var . If you do ...

When solve returns complicated solutions, or cannot return a solution, ... Try to reduce the number of equations, parameters, and variables.

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 which you specify these variables defines the order in which the solver returns the solutions.
