The solve function returns a structure when you specify a single output argument and multiple outputs exist. Solve a system of equations to return the solutions in a structure array. syms u v eqns = [2*u + v == 0, u - v == 1]; S = solve (eqns, [u v]) S …Select Numeric or Symbolic Solver. You can solve equations to obtain a symbolic or numeric answer. For example, a solution to cos ( x) = − 1 is pi in symbolic form and 3.14159 in numeric form. The symbolic solution is exact, while the numeric solution approximates the exact symbolic solution.Find the base of a triangle by solving the equation: area = 1/2 x b x h. You need to know the area and height to solve this equation. Put the area before the equals sign, and replace the letter h with the height.When A is a large sparse matrix, you can solve the linear system using iterative methods, which enable you to trade-off between the run time of the calculation and the precision of the solution. This topic describes the iterative methods available in MATLAB ® to solve the equation A*x = b. Direct vs. Iterative Methods
In this step, I am using the MATLAB backlash operator to solve the linear system Ax=b. The following statements have the same functionality (solve a system of linear equations): x = A\B x = mldivide(A,B) Provided that you have to use the Gauss-Seidel method to solve the linear system of equations, I will leave that modifications …Solve the system of non-linear equations. x^2 + y^2 = 2z. x^2 + z^2 =1/3. x^2 + y^2 + z^2 = 1. using Newton’s method having tolerance = 10^(−5) and maximum iterations upto 20 ... i need to solve 5 non linear equations with 5 unknowns in matlab so how i can write program for solving those equations.There are an infinite number of solutions to theta = acos (3/4). First of all there is the 2pi ambiguity, so theta = .7227 + 2*pi*n is a set of solutions. Then the negative angle, -.7227 (with its 2pi ambiguity) is a set of solutions as well. But note that the equations are symmetric under theta --> -theta, a<-->b.If the input eqn is an expression and not an equation, solve solves the equation eqn == 0. To solve for a variable other than x, specify that variable instead. For example, solve eqn for b. 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.

X = A\B solves the symbolic system of linear equations in matrix form, A*X = B for X. If the solution does not exist or if it is not unique, the \ operator issues a warning. A can be a rectangular matrix, but the equations must be consistent. The symbolic operator \ does not compute least-squares solutions. X = mldivide (A,B) is equivalent to x ...
