Then the function fun must return, in a second output argument, the Jacobian value J, a matrix, at x. If the Jacobian can also be computed and the Jacobian parameter is 'on', set by
x = myfun is a MATLAB function such as. The function fun can be specified as a function handle. fun is a function that accepts a vector x and returns a vector F, the nonlinear equations evaluated at x. The nonlinear system of equations to solve. This section provides function-specific details for fun and options: Returns the Jacobian of fun at the solution x.įunction Arguments contains general descriptions of arguments passed in to fsolve. Returns a structure output that contains information about the optimization. Returns a value exitflag that describes the exit condition. Returns the value of the objective function fun at the solution x. Pass an empty matrix for options to use the default values for options. Passes the problem-dependent parameters P1, P2, etc., directly to the function fun. Minimizes with the optimization parameters specified in the structure options. Starts at x0 and tries to solve the equations described in fun. = fsolve(.)įsolve finds a root (zero) of a system of nonlinear equations. \(0 1\), \(p\not\in\^n\), \(y>0\), \(x^*x/y\).Fsolve (Optimization Toolbox) Optimization Toolboxįor x, where x is a vector and F(x) is a function that returns a vector value. Unambiguously interpreted as convex or concave are accepted: Only those values of p which can reasonably and X^p and x.^p, where x is a real variable and and p The polynomial must be affine, convex, or concave, and Polyval(x,p) constructs a polynomial function of the variable If p is a constant and x is a variable, then. The combination must satisfy the DCP rules for addition Polyval(x,p) computes a linear combination of the elements of If p is a variable and x is a constant, then. This function can be used in CVX in two ways: Transpose and conjugate transpose: Z.', y'. Indexed assignment, including deletion: y(2:4) = 1,. Matlab’s basic matrix manipulation and arithmetic operations have beenĮxtended to work with CVX expressions as well, including: 
See the definitions of power in Nonlinear below. Numerous other combinations are possible, of course. An affine column vector CVX expression can be multiplied by aĬonstant matrix of appropriate dimensions or it can be left-dividedīy a non-singular constant matrix of appropriate dimension.
If the constant is positive, the curvature is preserved if
A CVX expression can be multiplied or divided by a scalarĬonstant. Two CVX expressions can be added together if they are of the sameĭimension (or one is scalar) and have the same curvature ( i.e.,. With both standard mathematical and Matlab conventions and the DCP ^ have been overloaded to work inĬVX whenever appropriate-that is, whenever their use is consistent Matlab’s standard arithmetic operations for addition +, subtraction -, See Power functions and p-norms for details on For irrational values of p, a nearby rational is selected Represents these functions exactly when \(p\) is a rational ( e.g., norm(x,p)) are marked with a double dagger (‡). Functions involving powers ( e.g., x^p) and \(p\)-norms. As this section discusses, this is an experimentalĪpproach that works well in many cases, but cannot be guaranteed. Of the successive approximation method, a warning will be issued. Solver, achieving the same final precision. 
Other solvers, these functions are handled using a successiveĪpproximation method which makes multiple calls to the underlying Most effectively by Mosek, the only bundled solver with support for theĮxponential cone upon which these functions are constructed. Models incorporating these functions will be solved Functions marked with a dagger (†) are not supported natively by manu.Place certain restrictions or caveats on their use: In some cases, limitations of the underlying solver In this section we describe each operator, function, set, and command that you are
