How to integrate numerically Z(t1,t2) ? My function is more complicated than cos but is analytical.
integral(integral(cos(t),-10,t) ,t1,t2)
F = @(t) cos(t);
A = @(t) -integral(F,-10,t)
Z = @(t1,t2) - integral(A,t1,t2)
Z(0,1)

The intermediate integration is numerical in nature so the operation needs to be vectorized. Unfortunately the integral function does not handle vectors for integral limits. Try the following
F = @(t) cos(t);
A = @(t) arrayfun(@(s)-integral(F,-10,s),s);
Z = @(t1,t2) -integral(A,t1,t2);
