CHAPTER 3
Basic MATLAB Functions for Linear and Non-Linear Optimization
3.1 Solutions of Equations and Systems of Equations
MATLAB allows you to solve equations and systems of equations using the commands below:
solve(‘equation’, ‘x’) | Solves the equation in the variable x. |
syms x; solve(equ(x), x) | Solves the equation equ (x) in the variable x. |
solve(‘eq1,eq2,…,eqn’, ‘x1, x2,…,xn’) | Solves n simultaneous equations eq1,…, eqn (in the variables x1,…, xn). |
X = linsolve (A, B) | Solves A * X = B for a square matrix A, where B and X are matrices. |
x = nnls (A, b) | Solves A * x = b in the sense of least squares, where x is a vector (x ≥ 0). |
x = lscov(A,b,V) | Solves A ... |
