Help : Unknown references
by WN 27 Mar '06

27 Mar '06

Hi, I am getting unknown references when I use \startformula \startalign[n=3] .... Some math ...... \stopalign \stopformula in conjunction with \placeformula[eqn1] \startformula .... math .. \stopformula See \in[eqn1] .... <----------- unknown reference It has something to do with the formulanumber not set, I know, but how do I fix this in the above ?? Thanks for your help and time WN

Feature Request: mathmatrix enhancement
by Aditya Mahajan 27 Mar '06

27 Mar '06

Hi, Is it possible to have allow math matrix column alignments to be configurable, on the lines of align={left,left} of \startalign. I want to be albe to say \startformula \startmatrix[align={right,left}] \NC x \NC = a + d \NR \NC y \NC = d \NR \stopmatrix \stopformula to give me x = a + d y = d This is a contrived example. The actual equation that I want to type is \startformula \text{Let }{\cal R} = \bigcup_{P_{X_1},P_{X_2}} \left\{ (R_1, R_2) : \startmatrix[distance=0.1em] \NC \hfill R_1 \NC < I(X_1 ; Y \mid X_2) \hfill \NR \NC \hfill R_2 \NC < I(X_2 ; Y \mid X_1) \hfill \NR \NC \hfill R_1 + R_2 \NC < I(X_1,X_2 ; Y) \hfill \NR \stopmatrix\right\} \stopformula All these manual hfills look ugly. Is matrix the wrong way to go about this? Should we rather have a aligned environment like amsmath? Or is there a simple alternative that I have overlooked?

List of builtin TeX commands
by Nikolai Weibull 27 Mar '06

27 Mar '06

Hi! Is there a list of builtin TeX commands anywhere on the net? I need it for a syntax definition of the plain TeX format. With builtin TeX commands I mean stuff like \def, \global, and such. A list of commands defined in plain.tex would be great as well, but at least that's easier to compile by myself, as I can just look in the actual file. The tex source is a bit harder to overview... Thanks! nikolai

Rows or columns on top in TABLE

Hello, the following creates a table with the even rows gray, but the lines between columns is only visible on the rows with no background.

What is the third parameter in \useURL for?
by John R. Culleton 24 Mar '06

24 Mar '06

For \useURL the first parameter identifies the statement, the second defines the url, the third is usually blank and the fourth gives the text to appear in the clickable area.

More on margin figs
by David Arnold 24 Mar '06

24 Mar '06

Hans et al, Maybe I am missing the point, but this example has output that is unexpected. There's a huge block of whitespace, that coincidentally continues to the bottom of the caption on the margin fig. Is this correct behavior? I thought if I put a margin fig out there, then the text should flow uninterrupted. %output=pdf \setupwhitespace[medium] \setupindenting[medium,yes] \definereferenceformat[infigure][text=Figure] \defineenumeration[definition] \useMPlibrary[dum] \starttext Readers will note that each object in the domain is paired with one and only one object in the range, as seen in the mapping diagram of \infigure[fig:graphmap]. \placefigure [inright][fig:graphmap] {A mapping diagram for $f$.} {\externalfigure[graph1][width=\marginwidth]} Thus, we have two representations of the function $f$, the collection of ordered pairs \in[collection], and the mapping diagram of in \infigure[fig:graphmap]. A third representation of the function $f$ is the graph of the ordered pairs of the function, shown in the Cartesian plane in \infigure[fig:graphmap2]. \placefigure [][fig:graphmap2] {A graph of the function $f$.}{\externalfigure[graph2]} When the function is represented by an equation or formula, then we adjust our definition somewhat. \startdefinition[def:graf] The graph of $f$ is the set of all ordered pairs $(x,f(x))$ so that $x$ is in the domain of $f$. In symbols, \startformula \hbox{Graph of $f$}=\big\{(x,f(x)):\,\hbox{$x$ is in the domain of $f $.}\big\}. \stopformula \stopdefinition This last definition is most easily explained by example. So, let's define a function $f$ that maps any real number $x$ to the real number $x^2$; that is, let $f(x)=x^2$. Now, according to \in{Definition}[def:graf], the graph of $f$ is the set of all points $(x,f(x))$, such that $x$ is in the domain of $f$. \stoptext
