that location loads extremely slow - even using a very fast connection it may need over 20 sec to load (and with a modem it is sometimes messy ...)

it seems it had become slow over the last weeks

I kept seeing in the help pages for linalg that it is being superseded by LinearAlgebra, so I have tried to work with LinearAlgebra. However, it turns out that LinearAlgebra is very clumsy and annoying for symbolic computations. LinearAlgebra was clear meant to be a numerical calculation package. Unfortunately, the desiderata for numerical calculations are not the same as for symbolic calculations. The main feature of LinearAlgebra which causes this clumsiness is the requirement that all elements of a Matrix be defined. To do symbolic calculations this means assigning a symbol to use with an index for the undefined elements of the Matrix. The name of this symbol has to be different from that of the Matrix itself, and the indexed symbol is not an array or a table or a Matrix. Already then you have two names for essentially the same thing. ==> First Problem. Now, lets say you do some calculations with these Matrices and end up with expressions that that contain the indexed symbolic names. To assign other values to these indexed symbolic names in the resulting expressions, you have to assign the indexed symbolic names new values and you cannot use matrix operations for that since these indexed symbolic names are not arrays or Matrices or even tables. ==> Second Problem. Now if you want to unassign the symbolic names again or assign new values and have these values show up in the original Matrices, you have to reassign the symbolic names and reassign the values in the original Matrices. (Matrix elements cannot be unassigned.) In other words, do the job twice. ==> Third Problem.

If you ever wanted to be able to download the manuals for Maple and other Maplesoft products, you now can download PDF versions of the manuals. Manuals include; Maple, Maple T.A., and MapleNet User Manuals, Maple 10 Quick Reference Cards, Maple Introductory and Advanced Programming Guides, and more. Download them all from the Maplesoft Documentation Center.

This book entry describes a method, using text files and preprocessor macros, to measure the timing and memory usage of Maple procedures. Attached are the source code and compiled library for a small Maple package that does the actual measurements.

It seems that Edit|Remove Output|From Selection just stopped working. Any ideas what happened? I don't know of any option that affects this that I could have changed unknowingly. However, From Worksheet works fine. I am working in standard worksheet mode with either 2D or 1D math input.

If the last entity in a worksheet is a Document Block, I can find no way to get a Worksheet execution group and prompt AFTER that Document Block. Have I missed something? I've searched all through the help system and forums with no luck. Of course, one could have had more foresight and have put the Document Block BEFORE a final Worksheet prompt. However, one would have hoped that, since there is a command to Creat Domument Block, theere would be a command to Exit Document Block. Using Insert Execution Group just puts the execution group into the Deocument Block. When caught in this predicament, the only way I could see to get out was to Remove the DB, put in an extra execution group at the end, and then recreate the DB without the last execution group.

I've been learning Maple 9.5 for a week now. There are many data types, and they each have their differences in functionality. I came across an article that mentioned that lists and sets make copies of the data for each manipulation, therefore aren't the best choices with that in mind. My questions is essentially: What are the subtleties of the different data types in speed and memory etc...? Which seem to work better is which situations? considering that we all want our code to be done now and take up no memeory :>) thanks James

This book page describes and compares several methods for sorting lists of names. It revisits using attributes for rapid sorting, with attention to their global effect on strings. It demonstrates the use of the lexorder[n] option to sort and it illustrates the use of convert/local.

In this episode Tom Lee sits down with John McPhee the inventor of Dynaflex Pro, in his office at the University of Waterloo to discuss dynamic models of physical systems, difficulties one might encounter when commercializing a product, and his work on modeling the piano hammer action. Paul Goossens joins us via telephone from the American Control Conference to talk about DynaFlexPro and other engineering products; and we bring you an interesting selection of news and mailbag items.

Maplesoft has just announced a public beta for a new product called the Maple Toolbox for MATLAB®. In many ways, it's a more advanced version of the Symbolic Math Toolbox™ produced by The MathWorks. You can get more info and download the software here. Note that you need a copy of MATLAB® on your machine. The discussion forum for the beta test will be right here in MaplePrimes. T4.

Suppose a function is given as f:=[[.4,.2,.7],[a,b,c]]. How this can be done that writing >f(a); would give me .4 Thanks.

I have a user defined type named FST which is like [list of numbers between 0 and 1 inclusive,list of names]. I now want to change union of two objects of type FST to be as maximum of evry pair of corresponding elemnts of first sublists. For example suppose A:=[[.3,.4,.2],[a,b,c]]; B:=[[.7,0,.2],[a,b,c]]; Then writing >A union B; should give [[.7,.4,.2],[a,b,c]] Thanking in anticipation.
