Consider the following two continued fractions $A$ and $B$:
$$\frac{\alpha_0}{1+a_0x-\frac{b_1x^2}{1+a_1x-\frac{b_2x^2}{1+a_2x-\cdots}}}$$ $$\frac{\beta_0}{1+c_0x-\frac{d_1x}{1+c_1x-\frac{d_2x}{1+c_2x-\cdots}}}$$
where $a_i,b_i,c_i,d_i$ and $\alpha_0,\beta_0$ are real numbers.
The first fraction $A$ is called J-fraction. Can I rewrite the second fraction $B$ in the form of J-fraction $A$?
Any suggestions, please?
