I saw something related to my question
uu = @(th) vif(th>ph0&th<ph1,umax*exp(1./((th-ph0).*(th-ph1)))/en,0)
but unfortunately, 'vif' is not defined. Please I need clarification.

Assuming that you have assigned a definite vector of values to th, then:
y = nan(size(th));
mask = th0 < th & th < th1;
y(mask) = umax*exp(1./((th(mask)-th0).*(th(mask)-th1)))/en;

Why do you want to write it that way?
Have you considered using piecewise() from the symbolic toolbox?
