How to bring my time varying workspace data to if else loop in matlab program editor?

ref is my workspace data and given as input to matlab function.

This is not working as i need!

I'm using matlab function

Program:

function betaref = fcn(ref)
min=1500;
max=150000;
for t=0:0.1:100
if (ref==0)
    y=45;
elseif (ref>max)
    y=90;
else
    y=0;
end
betaref=y;
t=t+1;
end

MATLAB function cannot see the base workspace data by default. You need to pass the data as input to the function.

It is given, but still I'm not getting it!
