iFit/xlim

 b = xlim(s, parameters, [min max], ...) : sets parameter bounds (min,max) for further fit using the model 's'

   @iFunc/xlim bound model parameters during further fit process.

   To bound a set of parameters, you may use a regular expression as:
     xlim(model, regexp(model.Parameters, 'token1|token2|...'), [min max])

   xlim(model, parameter, [min max])
     limit a parameter in model within [min max]. Inf and NaNs are ignored.
   xlim(model, parameter, [])
     remove the parameter bounds in model
   xlim(model, parameter)
     return the current parameter limits
   xlim(model)
     display bounded parameters

 input:  s: object or array (iFunc)
 output: b: object or array (iFunc)
 ex:     b=xlim(a,'Intensity',[0 1]);
