Help correct the error. I have the following error:

`TypeError: only length-1 arrays can be converted to Python scalars`

Code snippet where an error is issued:

` ``M = 216 t1 = np.linspace(a, b, M) f1 = np.interp(t1, z1, a1) f1_not_nan = f1 f1_not_nan[math.isnan(f1)] = np.array([])`

I think that there is a problem in `f1 = np.interp(t1, z1, a1)`

, but I don’t know how to fix it. If you have ideas, tell me.
