In particular the ``\d'' command is redefined, so care should be taken, expecially when including this package in an already existent LaTeX file.
The original work of ``\d'' (i.e. place a dot under its argument) is now done by the ``\UnderDot'' command.
At now, six options are available with the mathcmd package, which comes out in matched pairs.
The ``ThreeSubscrSum'' and ``TwoSubscrSum'' options control the placement of subscripts for the ``\Sum'' command: the latter (which is the default) puts the index under the simbol toghether with the starting point, while the former puts the index on the lower right corner.
The ``ProdVettWedge'' and ``ProdVettTimes'' options select which symbol is to be used for the vector product: the first one uses a ``\wedge'' (default), whilst the second uses a ``\times".
Finally, the ``VectOpStr'' and ``VectOpSymb'' options controls whether the vector-operator commands ``\Grad'', ``\Div'' and ``\Rot'' should produce a roman string (default) or a ``\nabla" symbol followed by an operator, respectively.
The mathcmd package defines a number of math-mode commands.
The ``\text...'' command is defined to be equivalent to ``\mbox'' (except when the ``amstext" package is also used, since this package already defines this command in a better way).
It is intended for inserting pieces of text in a formula.
The ``\Int'' (capitalized) differs from the LaTeX command ``\int'' in that it is always printed in displaystyle and if it has only a subscript, this is somewhat lowered so that it looks better.
\Int_{...}^{...} ... \d{...}
The ``\d...'' command is for making the differential symbol at the end of integrals: it simply prints a ``d'' followed by its argument and preceded by a little space, which seems prettier.
The ``\Sum{...=...,...}'' command works differently, depending on which option between ``TwoSubscrSum'' (default) and ``ThreeSubscrSum'' has been specified.
In the first case, it expands to ``\displaystyle\sum_{...}={...}^{...}'', whereas in the second case the second and third argument are treated in the same way as before (i.e. as a subscript and superscript, respectively), but the first argument (the one before the ``='') is placed near the lower-left edge of the ``\sum'' symbol and the ``='' is not printed.
There is also a ``\SUM...'' command which is useful when only a subscript is desired, irrespectively of the option specified: in fact, it is equivalent to ``\displaystyle\sum_...".
The commands ``\DerTot{...}{...}'', ``\DerPar{...}{...}'' and ``\DerNorm{...}'' generate the symbols of total derivative, partial derivative and normal derivative, respectively.
In other words, they are the same as:
\displaystyle\frac{d...}{d...}
\displaystyle\frac{\partial ...}{\partial ...}
\displaystyle\frac{\partial ...}{\partial n}
The command ``\TendsTo[...,...]'' generates a right-arrow with optionally an underscript wich is another smaller right-arrow between the two comma-separeted arguments inside the square brackets.
For example, the command ``f(x) \TendsTo[x,0] 1'' generates the following output:
f(x) ----------> 1 x --> 0
Finally, the commands ``\Grad'', ``\Div'' and ``\Rot'' generates the strings ``grad'', ``div'' and ``rot'' in roman type and with small spaces added before and after, if the ``VectOpStr'' option is in effect (default). If, instead, the option ``VectOpSymb'' was specified, they generate ``\nabla", ``\nabla\cdot'' and ``\nabla\ProdVett'' respectively.
The command ``\ProdVett'' is intended for making the symbol of vector product, and evaluates to ``\times'' with the option ``ProdVettTimes'' and to ``\wedge'' with the (default) option ``ProdVettWedge''.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
