Hi guys.

- The temputure array A is given (Y value) in hours,
- of course, X are uniformly distributed in hours, e.g x1 = 1, x2 = 2, x3 = 3. x4 = 4 ...
- e.g a1 = f(x1=1), a2 = f(x2=2), a3 = f(x3=3), ...

My question is, how to write this weather vs hour function ?

Note that, 1. this funcation must be a symfun type, (f is symfun, x is sym) because I need to give this symfun into the "int" function later.

2. since this funcation will feed into "int", I think it should be able to give any Y value for given X. e.g, Y = whatever number = f(1.64), this 1.64 is a number between x1 and x2, in other words, this function is not discrete (not spikes) but a continuous. It doesnt need to be "smoothly" continuous, even straight line connected is fine.

Thank you!
