%CONSTR Contrained optimization
%
%  x=constr('f',x0,options,xlow,xhigh,'g') finds the value of x for which 
%  the first output of f is minimal in the range constrained by f second output. 
%  f(x) should return two outputs : the first output is minimized subject 
%  to the second output being non-positive.
%  options is optional, giving the optimization arguments. If options
%  is the empty matrix, default options are used.
%  xlow and xhigh provide lower and upper bounds for x value.  g(x) provides 
%  the optional gradient of the function f(x). Optional arguments may be 
%  provided to f by passing them to constr after 'g'.
