I need to add an complex integral inside of a integral function like this:
integral(@(x)sin(integral(@(a)sin(a),0,x)),0,1)
However, it turns out to be an error with message: “Limits of integration must be double or single scalars.”
P.S. My function is much complex than 'sin(x)', here just is an example.
How to solve this?

Ran in:
format long
integral(@(x)sin(integral(@(a)sin(a),0,x)),0,1,'ArrayValued',true)
ans =
0.156096097878724
integral(@(x)sin(1-cos(x)),0,1)
ans =
0.156096097878724
