How to represent Hadamard gate as product of Rx and Ry gates? As simple as question asks - how to represent Hadamard gate as product of Rx and Ry gates assuming that values for rotation of Rx and Ry gate can be different?

We have
$$R_x(\pi)R_y(\pi/2)=\left(
\begin{array}{cc}
 0 & -i \\
 -i & 0 \\
\end{array}
\right)\left(
\begin{array}{cc}
 \frac{1}{\sqrt{2}} & -\frac{1}{\sqrt{2}} \\
 \frac{1}{\sqrt{2}} & \frac{1}{\sqrt{2}} \\
\end{array}
\right)$$
$$=\left(
\begin{array}{cc}
 -\frac{i}{\sqrt{2}} & -\frac{i}{\sqrt{2}} \\
 -\frac{i}{\sqrt{2}} & \frac{i}{\sqrt{2}} \\
\end{array}
\right)=-i\left(
\begin{array}{cc}
 \frac{1}{\sqrt{2}} & \frac{1}{\sqrt{2}} \\
 \frac{1}{\sqrt{2}} & -\frac{1}{\sqrt{2}} \\
\end{array}
\right)=-iH$$
This suffices for the purposes of quantum computing since the overall phase of $\frac{3\pi}{2}$ (represented by $-i$) doesn't effect the final measurement output.
