arrayssubfloats
what I've been trying to do is to pack multiple arrays on a single 'row', similar to what subfig module does with images (and tables, I guess); mostly to conserve space.
Something like this:
I would use tables and subfig instead of arrays, but I'm not sure how the parentheses would work.
Yes, it is possible. You need to set
\captionsetup[subfigure]{subrefformat=simple,labelformat=simple,listofformat=subsimple}
\renewcommand\thesubfigure{(\alph{subfigure})}
and to use \subref*. A complete example:
\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage[format=hang,singlelinecheck=0,font={sf,small},labelfont=bf]{subfig}
\usepackage{caption}
\usepackage[noabbrev]{cleveref}
\graphicspath{{figures/}}
\captionsetup[subfigure]{subrefformat=simple,labelformat=simple,listofformat=subsimple}
\renewcommand\thesubfigure{(\alph{subfigure})}
\begin{document}
\begin{figure}
\centering
\captionsetup{justification=raggedright}
\subfloat[text]{\label{fig:1a}\includegraphics{file1.eps}}\qquad
\subfloat[text]{\label{fig:1b}\includegraphics{file2.eps}}\\
\subfloat[text]{\label{fig:1c}\includegraphics{file3.eps}}\qquad
\subfloat[text]{\label{fig:1d}\includegraphics{file4.eps}}
\caption{\protect\subref{fig:1a} to \protect\subref{fig:1b} are plotted against height, and \protect\subref{fig:1c} to \protect\subref{fig:1d} against pressure}
\label{fig:1}
\end{figure}
Now I refer to the figure \subref*{fig:1d}. And use cref: \cref{fig:1d}
\end{document}
The demo option for graphicx simply replaces actual figures with black rectangles; do not use that option in your actual document.
By the way, I made some modifications to your code: to prevent errors, I \protected the \subref commands inside \caption. Also I removed the inner minipage since its use was not required in this particular example. I didn't load some packages that were not relevant for the issue discussed in this question.
I don't think using three different formats for the numbering of subfigures is good. Anyway, here it is:
\documentclass{article}
\usepackage{caption}
\captionsetup[figure]{labelsep=period,justification=centering,singlelinecheck=off}
\DeclareCaptionLabelFormat{rightparen}{#2)}
\usepackage{subfig}
\captionsetup[subfloat]{labelformat=rightparen}
\showcaptionsetup[uniq]{subfloat}
\usepackage{xparse}
\ExplSyntaxOn
\seq_new:N \g_akj_subfloat_seq
\NewDocumentCommand{\xsubfloat}{ m m }
{
\akj_subfloat:nn { #1 } { #2 }
}
\NewDocumentCommand{\makexcaption}{o}
{
\caption{\IfNoValueF{#1}{#1~}Subfigures:~%
\seq_use:Nnnn \g_akj_subfloat_seq {;~} {;~} {;~}}
}
\cs_new_protected:Npn \akj_subfloat:nn #1 #2
{
% initialize
\int_compare:nT { \value{subfigure} = 0 }
{ \seq_gclear:N \g_akj_subfloat_seq }
% do the subfloat
\subfloat[]{#2}
% store the subcaption
\seq_gput_right:Nx \g_akj_subfloat_seq { (\exp_not:N\textit{\alph{subfigure}}) ~ \exp_not:n { #1 } }
}
\ExplSyntaxOff
\renewcommand{\thesubfigure}{\textit{\alph{subfigure}}}
\makeatletter
\def\p@subfigure{\thefigure\,}
\makeatother
\begin{document}
\begin{figure}
\centering
\xsubfloat{subfigure A}{%
\rule{100pt}{50pt}%
\label{fig:subfig-a}%
}
\xsubfloat{subfigure B}{%
\rule{100pt}{50pt}%
\label{fig:subfig-b}%
}
\xsubfloat{subfigure C}{%
\rule{100pt}{50pt}%
\label{fig:subfig-c}%
}
\makexcaption\label{fig:figures}
\end{figure}
See Figures~\ref{fig:subfig-a}, \ref{fig:subfig-b} and~\ref{fig:subfig-c}.
\end{document}
The \makexcaption command has also an optional argument for text going before the list of subcaptions, so
\makexcaption[Some text.]
would produce
Figure 1. Some text. Subfigures: (a) subfigure A; (b) subfigure B; (c) subfigure C
Beware of unprotected end-of-lines in the arguments of \subfloat, that are the cause of your spurious spaces.

Just write the array in the same line, without a paragraph break or leaving the math environment, such as
resp. matrix environments.
