I try to calculate the integral of the Bessel function in Matlab

```
syms a r b k
L=int(log(r) * (besselj(0,a * r)+b * bessely(0,a * r)),k,1)

```

but I have this error (Invalid limits given : (k, 1)) i.e. I have a problem in log(r) but the k checks (0<k<1) I don't know how I can set this condition (0<k<1) to get the correct result. how can I calculate this integral with this condition in Mathematica?
