Maybe afm2tfm?

I printed the two fonts with ghostscript's 'ps2pdf prfont.ps':

The TeX-yhcmex10.pfb seems to have cmex10 in postions 0-127, and the 
yhmath glyphs in 128+, while yhcmex.pfa has just the yhmath glyphs in 
128+.  This suggests that the .vf should not be used with 
TeX-yhcmex10.pfb, so I renamed the file to:


In principle, however, it seems better to use the real cmex10 rather
than some copy embedded in TeX-yhcmex10.pfb.

The .dtx file from macros/latex/contrib/yhmath on CTAN uses
\matrix so appears to be older than the .sty file in fonts/yhmath,

< \newenvironment{amatrix}{\left\langle\matrix}{\endmatrix\right\rangle}

Also, the .sty uses a different definition of \widering:

< \newcommand{\widering}[1]{\overset{\smash{\lower1.333ex\hbox{$%
< \displaystyle\ring{}$}}}{\wideparen{#1}}}
> \newcommand{\widering}[1]{\overset{\smash{\vbox to .2ex{%
> \hbox{$\mathring{}$}}}}{\wideparen{#1}}}

I made these two changes to the .dtx file and get the same .sty 
file.  Running pdflatex also gives something that looks
very close to the original documentation (the original \widering has
more space between the ring and the horizontal parenthesis).
