Assume you have a matrix of 2x2 tikz figures and you decide to use subfloats. The code 
\documentclass{report} 
\usepackage{subfig} 
\usepackage{tikz}

... 
[horizontal-alignment] [vertical-alignment] [subfloats] [alignment]

The use of the additional subscript 1 on s below adversely affects the spacing afterwards: 
\documentclass{article} 
\begin{document} 
Actual: 
$\begin{array}{l} 
f_{s_1}(x) \\ 
f_{s}(x) 
\end{array}$ \\
