Hi all,
I am trying to line up some equations on a page and I'd like to insert
some whitespace that has the same width as a -ve sign in an equation.
An example would be trying to ensure the cosine and sine and on the
first and second rows (second column) in the matrix below:
\startpmatrix
% Row 1
\NC - \cos \theta_{\text{el}} \, \sin \theta_{\text{az}}
\NC \cos \theta_{\text{az}}
\NC \sin \theta_{\text{el}} \, \sin \theta_{\text{el}} \NR
% Row 2
\NC - \cos \theta_{\text{el}} \, \cos \theta_{\text{az}}
\NC - \sin \theta_{\text{az}}
\NC \sin \theta_{\text{el}} \, \cos \theta_{\text{el}} \NR
% Row 3
\NC - \sin \theta_{\text{el}}
\NC 0
\NC \cos \theta_{\text{el}} \NR
\stoppmatrix
Any ideas?
Thanks,
Graham
