Description
|
Used by Functions
|
attainfactor
|
The attainment factor at the solution x.
|
fgoalattain
|
exitflag
|
The exit condition. For the meaning of a particular value, see the function reference pages.
|
All functions
|
fval
|
The value of the objective function fun at the solution x.
|
fgoalattain, fminbnd, fmincon, fminimax, fminsearch, fminunc, fseminf, fsolve, fzero, linprog, quadprog
|
grad
|
The value of the gradient of fun at the solution x. If fun does not compute the gradient, grad is a finite-differencing approximation of the gradient.
|
fmincon, fminunc
|
hessian
|
The value of the Hessian of fun at the solution x. For large-scale methods, if fun does not compute the Hessian, hessian is a finite-differencing approximation of the Hessian. For medium-scale methods, hessian is the value of the Quasi-Newton approximation to the Hessian at the solution x.
|
fmincon, fminunc
|
jacobian
|
The value of the Jacobian of fun at the solution x. If fun does not compute the Jacobian, jacobian is a finite-differencing approximation of the Jacobian.
|
lsqcurvefit, lsqnonlin, fsolve
|
lambda
|
The Lagrange multipliers at the solution x. lambda is a structure where each field is for a different constraint type. For structure field names, see individual function descriptions. (For lsqnonneg, lambda is simply a vector as lsqnonneg only handles one kind of constraint.)
|
fgoalattain, fmincon, fminimax, fseminf, linprog, lsqcurvefit, lsqlin, lsqnonlin, lsqnonneg, quadprog
|
maxfval
|
max{fun(x)} at the solution x.
|
fminimax
|
output
|
An output structure that contains information about the results of the optimization. For structure field names, see individual function descriptions.
|
All functions
|
residual
|
The value of the residual at the solution x.
|
lsqcurvefit, lsqlin, lsqnonlin, lsqnonneg
|
resnorm
|
The value of the squared 2-norm of the residual at the solution x.
|
lsqcurvefit, lsqlin, lsqnonlin, lsqnonneg
|
x
|
The solution found by the optimization function. If exitflag > 0 then x is a solution; otherwise, x is the value the optimization routine was at when it terminated prematurely.
