So if I understand properly. You're actually imbedding images of worksheets into your Latex? This would not be an option for me as there will be a LOT of maple code include in what i'm preparing. Plus this will inflate the size of the .pdfs quite a bit.

There is no Maple 14/etc folder (at least on OS X).

I should mention that I *do* have the maple*.sty files in the folder along with the tex-file. That is, the latex is compiling fine, and despite this is producing blank output.

I'm inclined to agree with you John.

Completely agree. However, this is a stochastic process course (for non-programmers and non-mathematicians) and most of the students will only be able to use maple as a "symbolic calculator". We're trying to be very verbose with our code so they know exactly what happens. Although I think functional (or semi-functional in the case of maple) is more elegant; it is notoriously difficult to decipher.

I did something like this instead:

interface(quiet=true):
with(Statistics):
states := [ "S", "C", "R" ]:
#The probability distributions from transitioning OUT of a state
dist["S"] := ProbabilityTable([0.6, 0.3, 0.1]):
dist["C"] := ProbabilityTable([0.4, 0.5, 0.1]):
dist["R"] := ProbabilityTable([0.3, 0.4, 0.3]):
TransitionFrom := state -> states[ Sample( dist[state], 1)[1] ];

#starting from the 'sunny' state is arbritrary
TodaysWeather := "S";
WeatherHistory := NULL;
for i from 1 to 50 do    
    NextWeather := TransitionFrom( TodaysWeather );    
    WeatherHistory := WeatherHistory, NextWeather;   
    TodaysWeather := NextWeather;
end do:

cat(WeatherHistory);

As a side note. I'm having a lot of difficulty posting code into these windows. It doesn't format properly, and everything seems to want to double space. Advise?

Thanks Robert,

That's exactly what I needed to know. 

It's for the undergrads though; so I may put the for loop back in (although your version is definitely more efficient).  In this case exposition is more important than speed.

Thanks again,

Paul

This is nice, but how does one typset something like \MapleInput{x^2;} without Latex complaining? putting \verb|x^2| will not work, nor will any of the \text{} variants. I'm not even exactly sure how one inserts a "^"; \^ is a foreign character.
