I have a main equation that should be numbered and now I want to define the variables of the equations which may contain another set of equations. For example please have a look;
code:
\begin{align}
\label{eq:2.1}
&\frac{J_1(a k s)}{\sqrt{\pi } s}
\end{align}
\begin{align*}
\text{where} ~& \text{\textsl{a} is lens radius}\\
& \textsl{k}=\frac{2 \pi }{\lambda }\\
& \textsl{s}=\sqrt{\left(\frac{u}{z_2}+\frac{x}{z_1}\right){}^2+\left(\frac{v}{z_2}+\frac{y}{z_1}\right){}^2}
\end{align*}
Result:
As we can see there is more than 2 line spacing (white space ) between the Eqn 2.1 and the variable definitions … is there any other efficient way to define variables of equations without numbering them … Or sub equation them as 2.1.1 , 2.1.2 etc …
