Matlab Tutorial 5: Linear Equations. In this Matlab tutorial we will deal with linear equations, the least square method, condition numbers over & under-determined equations. Let’s start with an example. Example 1. We have an equation system with three unknown variables and three equations. What will be the solution to the system below? 3w-2y ...

Equations and systems solver collapse all in page Support for character vector or string inputs has been removed. Instead, use syms to declare variables and replace inputs such as solve ('2*x == 1','x') with solve (2*x == 1,x). Syntax S = solve (eqn,var) S = solve (eqn,var,Name,Value) Y = solve (eqns,vars) Y = solve (eqns,vars,Name,Value)

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 = struct with fields: u: 1/3 v: -2/3.

Similar considerations apply to sets of linear equations with more than one unknown; MATLAB ® solves such equations without computing the inverse of the matrix. Although it is not standard mathematical notation, MATLAB uses the division terminology familiar in the scalar case to describe the solution of a general system of simultaneous equations.

For example, the paramfun helper function at the end of this example creates the following equation system parameterized by c: 2 x 1 + x 2 = exp ( c x 1) - x 1 + 2 x 2 = exp ( c x 2). To solve the system for a particular value, in this case c = - 1, set c in the workspace and create an anonymous function in x from paramfun.

Y = solve( eqns , vars ) solves the system of equations eqns for the variables vars and returns a structure that contains the solutions.
