MATLAB: Error while using fuzzy logic controller in a simulink model

fuzzy logicfuzzy logic controllersimulink

Hi,Help please,i use fuzzy logic controller in a simulink model and i build the entire flc from the command line using Fuzzy Logic Toolbox commands.when i try to run my Simulink model, i obtain this error:
MF 'trampf' does not exist!
??? Error using ==> evalfismex
Exiting ...
Error in ==> evalfis at 84
[output,IRR,ORR,ARR] = evalfismex(input, fis, numofpoints);
this is my code:
%FuzzyControlu1
a=newfis('FuzzyControlu1');

Just like the error says, there is no membership function trampf, but there is a membership function trapmf (trapezoidal membership function).
Fix this typo in your code and everything should work.
