I am not receiving email notifications from subscribed threads since about two days ago, without any change on my side. Has anyone else experienced this same problem?

I have noticed that for 3d plots with a lot of info, when I export them to eps format and subsequently view them, say with adobe acrobat, the figure is filled in sort of from the back to the front. There are points in the rear of the figure (or what was the rear in the original) that are subsequently overwritten by points in the foreground. Thus, it seems that exported eps of 3d Maple plots have some sort of 3d info in them.

I've been using a combination of Fortran and gnuplots to do my plots. my research required an intensive amount of data plotting. I've been trying to use maple to do scatterplots and curve fitting for my data. here is the code: > K := readdata("/Users/xxx/Work/dt40s5l10.110/ALL/dt40s5l10.110.1.DFIR.AVE", 8) # the file contains 2972 lines and 8 columns of data > unassign('G', 'X'); > seq(assign(G[i], (K[i+1, 5]-K[i, 5])/(K[i+1, 1]-K[i, 1])), i = 1 .. 2970); # to calculate the derivative > seq(assign(X[i], K[i, 1]), i = 1 .. 2970); when I tried to plot X vs G using scatterplots

hi to all here in this site..i just wanna ask  about algorithms..hope you can help me..

i need your help and evaluate our new develop algorithm if our algorithm is valid or not in terms of sorting numbers and characters. and as claim a fatest to sort..

whoever wants to evaluate our new algorithm,please email this: abegail_228710@yahoo.com..i look forward for the people wants to help us..

Last week was rather crazy…

Monday afternoon, I’m sitting in a canoe on a beautiful lake in the wilds of Ontario…

…Tuesday morning, I’m in Stuttgart for the Vehicle Dynamics Expo to introduce MapleSim 2 to the many automotive engineers that have converged from just about every European nation, and beyond, to learn about new technologies and methodologies for the design of vehicle chassis systems, including  suspensions, steering, tires (or tyres, depending where you come from), and braking systems. One hot topic of discussion is the rapid development of vehicle stability controllers, given that all new passenger vehicle designs must now by law include active stability control. This is very timely for us because we are able to show our hardware-in-the-loop (HIL) demonstration that includes a full-vehicle model developed in MapleSim and running on dSPACE and National Instruments PXI real-time platforms, with a MotoTron prototype controller interfaced to the vehicle model via a CANbus interface. I’ll describe this in more detail in a later blog post.

I have defined a sparse matrix and verified that it is space by using the command- sparsematrixplot(Kd,'matrixview');

first, is there another way to check wether the matrix is stored in the sparse form?

second, when trying to sovle an algebraic set of equation using the procedures for hendling the sparse matrix i encountered the following error:

Error, (in HWcall[1]) column vector dimension less than length of sparse data
 

what is the meaning of this error and how can I repair it?

“Keep Austin weird” is probably the best civic slogan I have ever encountered. Austin, Texas is one of the most charming cities in the US. It’s the capital of the state of Texas and also the self-professed live music capital of the world. In addition, the University of Texas at Austin is the largest university in the US, and its influence on the technology sector has spun off a very vibrant high technology business center as well. This mix of government, the arts, academia, and technology is the quintessential recipe for a very dynamic, vibrant, and yes, weird (in a good way) community.

Good morning!

I am currently involved (though hopefully near the end) in a lengthy discusion regarding how to use the mapleprimes editor. I should say up front that I am grateful for any forum that provides me a place to ask questions and to help others. I've been around for a few years, but only lately have I decided to put substantial effort into learning Maple. And it is a substantial effort, despite the Maple ads about how easy Maple is to use.

I just entered an equation, theta := pi/4. Maple returned 1/4 pi. I know that's the same, but not the way I'd expect to see it. In Mathcad, I can put anything I want (OK, no ice cream flavors ;-) ) to the right of the result, and the result is then re-displayed in those units. It isn't without a few peculiarities of its own, but I'd like to see pi/4, not 1/4 pi.

I have to keep moving my hands to the arrow keys to move in the numeric fields. For example, suppose that I am in the exponent and I want to drop down for the next operation. My hands are already on the space bar, and it is natural to want to use my thumbs. I understand that this might mean that I couldn't use space for implicit multiplication, but I don't want to use that nearly as often as I want to move in the numeric field, and I am most likely to use hard coded multiply anyway. Erring on the side of caution and all that.

Ever since I filled out my university application papers, I’ve been faced with the cocktail party question, “So, why did you decide to study engineering?” It’s not surprising, of course, given the low number of women who choose to enter the fields of math or engineering. I’ve actually been asked this question so often that I have a stock answer which I can pull out without having to think about it: When I was considering my field of study, I was equally drawn to the arts and the sciences, but it made more sense to prepare myself to work
in a field where the jobs were. Engineering seemed a good fit, and still provided a sort of outlet for my creative impulses. Plus, it would be easier to pursue art and music as a hobby, rather than anything scientific; it would be much harder to find the resources to pursue any scientific interests on my own.  Why electrical engineering? I’d heard it involved more math, something I was drawn to.

hi all,

                            I  have a program written using Matlab, how can I change it into a program written using Maple.

the program:

function [xmin, fxmin, iter] = PSO

I was just reminded of an aspect of Maple GUI Components, new to Maple 13, that has sometimes come in very useful to me. It is the ability to refresh a component programatically.

I should explain. The old (and current default) behaviour is for the GUI not to refresh any other components until the current component is finished (ie. returns control).

The relevant situation in which this matters is when a given component has action code whose

Well so far i liked maple, it's all fine! But when i load a proc with some char's like \n, whitch is linefeed - and i need that. it loads as being \134n!

Is there anything i can do to prevent this?
