Definite integration in matlab with the limits changing ?

Hello @all -how can i achieve this:-

%Integrate the function with changing limit

%limit of intigration
lowerlimit=0, upperlimit=z;
% Please note upperlimit z is a array & z varies from 0 to some positive value,let say 5.

%function
f=(-1.99)/(1.99-2*exp(-0.01*u)-1.98*exp(-2*u)); % u is a dummy variable

Thank you in advance.

Try this:

f =  @(u) (-1.99)./(1.99-2*exp(-0.01*u)-1.98*exp(-2*u)); % u is a dummy variable
z = 0 : 5;
for k1 = 1:numel(z)
    intf(k1) = integral(f, 0, z(k1));
end

You could also use the arrayfun function. The loop is much faster than arrayfun.

Experiment to get the result you want.
