The convert function with options will reduce your result even further: >convert(int(sec(x)^2, x),tan); Regards, Georgios Kokovidis Dräger Medical

On my PC, in the temp directory, I created a test filed called testdata2.dat. The file looks like this if you open it. R1 R2 0.4059 61.155616 0.406 67.890816 0.4061 71.123712 0.4062 71.39312 0.4063 69.911376 0.4064 67.082592 0.4065 64.119104 0.4066 61.425024 0.4067 59.404464 0.4068 58.326832 0.4069 58.326832 0.4070 59.000352 In Maple, I read it in like this: >restart: >RD:=readdata(`c:/temp/testdata2.dat`,2); >RD; >nops(RD); >X:=[seq(RD[i,1],i=1..nops(RD))]; >Y:=[seq(RD[i,2],i=1..nops(RD))]; Now you can process the X and Y data to create new variables as you see fit.

It sounds like Luna is using the Symbolic Toolbox under Matlab R2007a. To get a list of all of the Tollboxes that are loaded with version numbers, you can type "ver" at the Matlab prompt and hit the return key: >>ver Regards, Georgios Kokovidis Dräger Medical

Generally speaking, if you wish to take advantage of multiple cores for speed w.r.t Matlab or Maple, you will need to use specialized toolboxes for each that explicitly take advantage of the multiple cores and break up the problem so that it executes in a true parallel fashion. For more info on this regarding Matlab and Maple, see the links below. There is a cost ($$$) associated with each. As with any problem that needs to be solve, there is a trade off whether or not the cost in dollars is worth while relative to the speed advantages offered by having multiple processors solve the problem.

To elaborate further on acers' comment above: whattype(s); produces '+' as an output. whattype(t); produces 'series' as an output. ?whattype for more help on this. Regards, Georgios Kokovidis Dräger Medical

Sorry about my original post. I tried to edit but you beat me to it. I was a bit hasty. The following works for me without the original error. > restart: > with(LinearAlgebra): > A := <<1,0,0>|<2,1,0>|<1,0,0>|<-1,-1,-3>>: > b := <2,-1,-9>: > ans:=LinearSolve(A, b,free='S') assuming S::real; Regards, Georgios Kokovidis Dräger Medical

Try replacing free=R with free='R' (single quote around the R) and see what happens. Regards, Georgios Kokovidis Dräger Medical

Take a look at a previous posting here. Regards, Georgios Kokovidis Dräger Medical

This will work only if you have Maple loaded on the host machine. The original poster question was how to make the presentation available to any machine, by loading it onto a USB stick and taking it with you on the road when traveling. If a free Maple "reader/player" existed that had this capability, then that would be the way to go. Regards, Georgios Kokovidis

I am on a Windows machine. I unzipped the JavaViewLib into the following directory: c:\temp\Maple\JavaViewLib Go to your installation directory that Maple is loaded. There will be a directory called "Users". Within this directory there will be a .ini file. I am using Maple 10 for this example, so there is a file called maple10.ini. Open your favorite text editor and create another file called maple.ini in the same directory. Again, just to test this, my maple.ini file has the following line in it: libname := libname, `c:/temp/Maple/JavaViewLib`: Once I start Maple, the first thing it does is check the maple.ini file in the Users directory. Then when I type libname at the maple prompt, I get this; >libname; "C:\EngineeringApps\Maple9/lib", "c:/temp/Maple/JavaViewLib" My path from the .ini file shows up in the libname after executing the command. If it does not, then the package will not load using the "with" command. Notice the forward slashes and the ` in the path statement. The ` is under the tilde. From the help file on JavaViewLib you will also need to obtain a license and let the software know where your browser lives. Good luck. Regards, Georgios Kokovidis Dräger Medical

Greetings. Take a look at the JavaView page. Besides allowing you to view animations, it also allows you to manipulate your plots dynamically as if you were in the Maple environment. Hope this helps. Regards, Georgios Kokovidis Dräger Medical

The concept of Tables in Mathcad is different from a visual standpoint that what you are trying to do with the "table" function is Maple. In Mathcad you insert a "Component..." and select the component as a table, which looks like a mini spreadsheet. You can do the same thing in Maple by inserting a spreadsheet. Go to the menu bar, and select Insert and then Spreadsheet. To get more details as to how to enter data and manipulate the data (or symbols) within the spreadsheet, take a look at the help pages. This is the closest equivalent to Mathcad that Maple offers in this area. >?spreadsheet Regards, Georgios Kokovidis Dräger Medical

I think there is a small typo in the code above posted by Jacques. As is, it does not work. The offending line has "4=..nops" in it. What works for me is "i=4..nops". Regards, Georgios Kokovidis Dräger Medical

At the top of the worksheet, on the menu bar you will notice an icon that looks like 3 exclamation marks together. I use it all the time to execute the entire worksheet, top to bottom, especially when there is a restart command at the beginning of my worksheet. This saves me all kinds of grief as I add more and more commands to an existing worksheet and I do not see the results that I know I should get. Give it a try, and let me know what happens.

>restart; >with(plots): >g1 := plot( 4-(x-2)^2,x): >g2 := plot( x/2,x ): >display( [ g1,g2 ] ); Implicitplot is for functions of two variables. All you need is the plot function here, and the variable that you are plotting against (x). Take a look at the help files for the plot command and for the implicitplot command to see the differences. >?plot >?implicitplot Regards, Georgios Kokovidis Dräger Medical
