Re: [NTG-context] Bug in math alignment
Hi Mikael,
Thanks for your reply.
Indeed with your hint the issue disappears.
I’ll change my definition…

I think in this case it is better to use a mathsimplealign instead of a matrix.

\definemathsimplealign[collected][

right=\stopmathfenced,

strut=yes,
]
\starttext
\placeformula
\startformula
\startpdeproblem
\NC - \Delta u \NC = 0 \NC \qquad\text{in } \Omega \NR
\NC \frac{\partial u}{\partial {\bi n}} \NC = V u + \phi \NC
\qquad\text{on } \partial\Omega \NR

Re: [NTG-context] Bug in math alignment
Dear Jeong,
Thanks for testing my example, and pointing to the solution using \dm (which I
didn’t know…).
I think the correct behaviour of math alignments should avoid using additional
commands such as \dm.
We’ll see what Hans and Mikael say.
Best regards: OK

I confirm what you said.
However, if I use \dm{} instead of \displaystyle as following, then the output
is correct.
\placeformula
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC \dm{\frac{\partial u}{\partial {\bi n}}}
\NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula
or this (with\type{\displaystyle} added)
\placeformula
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC \dm{\frac{\partial u}{\partial {\bi n}}}
\NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula
In this example, it is OK to use \dm inside of \startformula … \stopformula.
I am not sure that it is what Hans and Mikael want.
Thanks,
Best regards,
Dalyoung

[NTG-context] Bug in math alignment
Hi Hans and Mikael,
I think there is an issue with the size of math fonts in \frac when used in
math alignments, as it is is shown in the following example.
%% begin bug-mathalignment.tex
\definemathmatrix[alignedcases]
[align={1:right,2:left,3:left},
distance=3pt,
left={\left\{},
right={\right.},
style=\displaystyle]
\starttext
Consider this
\placeformula
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC \frac{\partial u}{\partial {\bi n}} \NC = V u + \phi \NC \qquad\text{on
}\, \partial\Omega. \NR
\stopalignedcases
\stopformula
or this (with\type{\displaystyle} added)
\placeformula
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC \displaystyle\frac{\partial u}{\partial {\bi n}} \NC = V u + \phi \NC
\qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula
Actually, one should have this
\startformula
\frac{\partial u}{\partial {\bi n}} = V u + \phi \qquad\text{on }\,
\partial\Omega.
\stopformula
If one adds \type{\displaystyle} both to the numerator and denominator of
\type{\frac}, the result is correct:
\placeformula
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC \frac{\displaystyle\partial u}{\displaystyle\partial {\bi n}} \NC = V u +
\phi \NC \qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula
\stoptext
%% end bug-mathalignment.tex
