A, b  The matrix A and vector b are,
respectively, the coefficients of the linear inequality constraints
and the corresponding rightside vector: A*x ≤ b .  fgoalattain , fmincon , fminimax , fseminf , linprog , lsqlin , quadprog

Aeq, beq  The matrix Aeq and vector beq are,

C, d  The matrix C and vector d are,
respectively, the coefficients of the over or underdetermined linear
system and the rightside vector to be solved.  lsqlin , lsqnonneg

f  The vector of coefficients for the linear term in the
linear equation f'*x or the quadratic equation x'*H*x+f'*x .  linprog , quadprog

fun  The function to be optimized. fun is
either a function handle to a file or is an anonymous function. See
the individual function reference pages for more information on fun .  fgoalattain , fminbnd , fmincon , fminimax , fminsearch , fminunc , fseminf , fsolve , fzero , lsqcurvefit , lsqnonlin

goal  Vector of values that the objectives attempt to attain.
The vector is the same length as the number of objectives.  fgoalattain

H  The matrix of coefficients for the quadratic terms in
the quadratic equation x'*H*x+f'*x . H must
be symmetric.  quadprog

lb, ub  Lower and upper bound vectors (or matrices). The arguments
are normally the same size as x . However, if lb has
fewer elements than x , say only m ,
then only the first m elements in x are
bounded below; upper bounds in ub can be defined
in the same manner. You can also specify unbounded variables using Inf (for
lower bounds) or Inf (for upper bounds). For example,
if lb(i) = Inf , the variable x(i) is
unbounded below.  fgoalattain , fmincon , fminimax , fseminf , linprog , lsqcurvefit , lsqlin , lsqnonlin , quadprog

nonlcon  The function that computes the nonlinear inequality and
equality constraints. Passing Extra Parameters explains how to parameterize the
function nonlcon , if necessary. See
the individual reference pages for more information on nonlcon .  fgoalattain , fmincon , fminimax

ntheta  The number of semiinfinite constraints.  fseminf

options  A structure that defines options used by the optimization
functions. For information about the options, see Optimization Options Reference or the individual function reference
pages.  All functions 
seminfcon  The function that computes the nonlinear inequality and
equality constraints and the semiinfinite constraints. seminfcon is
the name of a function file or MEXfile. Passing Extra Parameters explains how to parameterize seminfcon ,
if necessary. See the function reference pages for fseminf for more information on seminfcon .  fseminf

weight  A weighting vector to control the relative underattainment
or overattainment of the objectives.  fgoalattain

xdata, ydata  The input data xdata and the observed
output data ydata that are to be fitted to an equation.  lsqcurvefit

x0  Starting point (a scalar, vector or matrix). (For fzero , x0 can
also be a twoelement vector representing a finite interval that is
known to contain a zero.)  All functions except fminbnd and linprog 
x1, x2  The interval over which the function is minimized.  fminbnd
