Hi guys,
I want to have the following integral in my equation: where 0 is the beginning and t=120 is the ending of the integral, ∫x*(1-e^t), where t is time in seconds.
ytot = 60 * ( 80*22 + 29.7*11 + integral(x*(1-exp(120))))
I hope you understand what I mean,
thanks for your help

Which variable are you integrating with respect to, x or t? It makes a lot of difference which one you mean.

Is ‘x’ a function of ‘t’ = ‘x(t)’?

I’m not certain what you want to do.
Try this:
t = 0:120;
ytot = 60 * ( 80*22 + 29.7*11 + integral(@(x)x*(1-exp(t)), min(t), max(t), 'ArrayValued',1));
