Math & Science ⇒ Subequation whitespace

[jvm]

Hello

I'm using subequation in one of my chapters, now I see there is a very big white space between my two equations a and b.

How can I limit the whitespace (preferably I just put them right under each other with a normal rule whitespace)?

MWE:

Code: Select all

\documentclass[a4paper,fleqn]{book}
% Packages
\usepackage{polynom,amssymb,amsmath}

\begin{document}


% Dutch style of paragraph formatting, i.e. no indents. 
\setlength{\parskip}{1.3ex plus 0.2ex minus 0.2ex}
\setlength{\parindent}{0pt}

\section{Partial Least Squares} \label{sec:PLS}
Partial Least Squares (PLS) is a method that defines orthogonal latent variables to compress the information and throw away irrelevant stuff. It maximizes the the covariance between $\mathbf{X}$ and $\mathbf{Y}$. PLS decomposes $\mathbf{X}$ ($n \times N$) and $\mathbf{Y}$ ($n \times M$) into te form as follows:
\begin{subequations}
  \begin{equation} 
	\mathbf{X} = \mathbf{T}\mathbf{P}^{T} + \mathbf{E} 
  \end{equation}
  \begin{equation} 
	\mathbf{Y} = \mathbf{U}\mathbf{Q}^{T} + \mathbf{F} 
  \end{equation}
\end{subequations}

Hi,

try with this:

Code: Select all

\begin{subequations}
  \begin{align} 
   \mathbf{X} &= \mathbf{T}\mathbf{P}^{T} + \mathbf{E}\\
   \mathbf{Y} &= \mathbf{U}\mathbf{Q}^{T} + \mathbf{F} 
  \end{align}
\end{subequations}

or with something like this (change -3pt according to your taste) if you want to reduce even more the vertical spacing:

Code: Select all

\begin{subequations}
  \begin{align} 
   \mathbf{X} &= \mathbf{T}\mathbf{P}^{T} + \mathbf{E}\\[-3pt]
   \mathbf{Y} &= \mathbf{U}\mathbf{Q}^{T} + \mathbf{F} 
  \end{align}
\end{subequations}

Lol that was easier than I thought

Thanks for the fast reply
