Hi Alejandro:

just to chime in with my 2 cents here...

I didn't interpret Acer's narrative as even remotely similar to Wolfram's... Ironically, he's usually the first (!) to tackle questions that require some changes/tinkering with maple's internals - as is the case with my current question.

I think we have to be realistic about the "openness" of Maple - it is not an open source project - it's a closed source platform, with its main goal being that of making money for Maplesoft. This is completely fine... (even though far from optimal for many users).

IMO the best way to ensure the existence of fully open and transparent tools, is to contribute to the various open projects that have been slowly gaining momentum over the last few years - SAGE seems like a good choice...

 

@acer 

thanks for your answer... seems more time consuming that i can afford right now, but maybe will look at this in the future if it doesn't get picked up during the next point release.

@acer 

ok, so to be clear, I guess you you mean that, if I say have an mla file that contains some module named Foo, there is no way for me to print all the source code of that module?

 

@acer 

thanks - that's what i suspected. How would I see the whole module then? I.e. the full code for everything that I need in order to redifine my own version of Explore. Is that possible?

thanks!... (sorry if this is in the docs - if so, i am not able able to find it).

@acer 

Hi Acer:

this bug aside, do you have any idea why redefining the "Explore" command by showing its code with "showstat" and then re-declaring with a different name is not working for me? it seems to have worked before with other simpler commands that I've tried this with (say Grid:-Map, or even the old Explore in maple 15 - using your suggestion in fact - see this post http://www.mapleprimes.com/questions/125305-Explore-Command  )

thanks

 

@acer 

I am using maple 2015.

Here is a trivial example that shows what I mean:

Explore(plots:-display(Matrix((i,j)->plot(sin(a*x), x=0..5),4,4), labels=["x", "this is y"]), parameters=[a=1..2], placement=left, size=[1200, 1000]);

Attaching two screenshots, the first shows what things look like by default, and the second, when I switch (via right hand menus) the alignment of the table column where the plots are to "Left"

thanks.

 

 

good find - please submit a bug report here:

i thought this post would be hitting mid 50s in responses by now, with everyone wanting to share their init.mpl equivalents... no?!  

where did i go wrong?!  ...  haha ;)

@Carl Love

My guess is that the method you describe is probably more flexible than what's provided in the Finance package, but for some problems the Finance package is really quite nice to use.

The documentation is also very good, so you should easily find many examples of how to use the stochastic solver there. A good start might be:

I wanted to attach a simple worksheet that I compiled in the past and that contains some examples, but I am not able to upload it - on two different browsers I get "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable." message... I give up...

just a follow up to acer's suggestion.

for me, in some odd situations ctrl+del does not work then the cursor is on/in the iterm i want to delete. What helps usually is to create an execution grou before this item with ctrl+k, move the cursor there, and only then press ctrl+del (a few times).

@Kitonum

thanks for the post... i think acer' suggestions above will work better for me, as they get rid of the "unwanted" part of the axes automagically, but neat idea nevertheless!

@acer

thanks very much for the workarounds- i think some combination of these will work well for me. The above was just a dummy example, I have to prepare ~10 plots all with different ranges/datasets and slightly different options.

 

 

could maybe a maplesoft employee confirm that it's not possible then?

thanks!

@Kitonum 

i don't think a set guarantees order. You might be safer using a list like so:

Sys:=[x+y=1, x+z=2, y+z=3]:



Archimedes should have probably told the king to first at least attempt his own (aghem..  homework... aghem..) problems, and that he'll be happy to help once the king has made some effort and is simply stuck... wink, wink.
