Design a fuzzy system to approximate a function

the function may not be defined analytically

but the values of the function in n point is defined

for example : x E [-3 3] g(x)=sin(x)

the approximation is calculated a fuzzy set design

our fuzzy function approximates sin function with an error

less than 0.2

note : this program uses a function named isinrange so copy it

to your directory-Design a fuzzy system to approximate a function
