function out=addmf(fis,varType,varIndex,MFLabel,MFType,MFParams)
%  Synopsis
%  a = addmf(a,varType,varIndex,mfName,mfType,mfParams)
%  
%  Description
%  A membership function can only be added to a variable name for an FIS that 
%  already exists. Indices are assigned to membership functions in the order 
%  in which they are added, so the first membership function added to a 
%  variable will always be known as membership function number one for that 
%  variable. You cannot add a membership function to input variable number two 
%  of a system if only one input has been defined. 
%  The function requires six input arguments in this order: 
%      A MATLAB variable name of a FIS structure in the workspace 
%      A string representing the type of the variable you want to add the 
%         membership function to (input or output)
%      The index of the variable you want to add the membership function to
%      A string representing the name of the new membership function
%      A string representing the type of the new membership function
%      The vector of parameters that specify the membership function.
%  
%  Example
%  a=newfis('tipper');
%  a=addvar(a,'input','service',[0 10]);
%  a=addmf(a,'input',1,'poor','gaussmf',[1.5 0]);
%  a=addmf(a,'input',1,'good','gaussmf',[1.5 5]);
%  a=addmf(a,'input',1,'excellent','gaussmf',[1.5 10]);
%  plotmf(a,'input',1)
