Minimize a function of one variable.
FMIN('F',x1,x2) attempts to return a value of x which is a local
minimizer of F(x) in the interval x1 < x < x2. 'F' is a string
containing the name of the objective function to be minimized.
FMIN('F',x1,x2,OPTIONS) uses a vector of control parameters.
If OPTIONS(1) is nonzero, intermediate steps in the solution are
displayed; the default is OPTIONS(1) = 0. OPTIONS(2) is the termination
tolerance for x; the default is 1.e-4. OPTIONS(14) is the maximum
number of steps; the default is OPTIONS(14) = 500. The other components
of OPTIONS are not used as input control parameters by FMIN. For more
information, see FOPTIONS .
FMIN('F',x1,x2,OPTIONS,P1,P2,...) provides for up to 10 additional
arguments which are passed to the objective function, F(X,P1,P2,...)
fmin('cos',3,4) computes pi to a few decimal places.
fmin('cos',3,4,[1,1.e-12]) displays the steps taken
to compute pi to about 12 decimal places.
