function out = Tanvismembershipfunction(x, params)
for i=1:length(x)
if x(i)<params(1)
y(i)= 2 * abs(x(i) - 0.5);
elseif x(i)<params(2)
y(i)= 2 * abs(x(i) - 0.5);
else x(i)<params(3)
y(i)= 2 * abs(x(i) - 0.5);
end
out=.1*y'; % scaling the output to lie between 0 and 1

There is no way to get that graph by just altering the params() values in that code.
Instead consider
y = 2 * abs(x - 0.5)

In my plot should be 3points..
In sequence at 1,0,1 on y-axis..
But i am getting like 0.1 0 0.1
I given parameters [0 0.5 1]
Range [0 1] , dispay range [0 1]
and i modified the code above..

Change the 2 to 20 if you insist on using that function structure

If you want to use it in a fuzzy logic/control problem, TRAPMF or TRIMF can easily create the function like that.
x=0:0.1:1;
y=1-trimf(x,[0 0.5 1]);
plot(x,y)

sorry, but i want to create the same thing without function...
x = 0:0.1:1
for i=1:length(x)
if x(i)<params(1)
y(i)= 2 * abs(x(i) - 0.5);
elseif x(i)<params(2)
y(i)= 2 * abs(x(i) - 0.5);
else x(i)<params(3)
y(i)= 2 * abs(x(i) - 0.5);
end
end
out=.1*y';
plot(x,out)
This works well in command window but not in fuzzy GUI... problem is mensioned in aboves answer..
