I installed the Maple Toolbox for MATLAB, I have both Maple 13 & MATLAB r2009b, so when I try to run the command syms I get this: syms x y ??? Error using ==> sym.sym at 164 Attempt to execute SCRIPT maplemex as a function: /Applications/MATLAB_R2009b.app/toolbox/maple/maplemex.m Error in ==> syms at 57 assignin('caller',varargin{i},sym(varargin{i})); I don't know what the hell is happening I have been trying to do everything but nothing have worked. I am on Mac OS X 10.6.2. What is going on with this issue? Thanks in advance.

Hi there, The Maple 11's Matlab link toolbox is not compatible with the Matlab(2007a) 's Symbolic toolbox at all. I previously had a code using Symbolic toolbox and it gave correct results, but now after upgrade it to Maple 11's Matlab link toolbox the results got completely wrong. I have a feeling that in order to speed up calculation, the Maple 11 Matlab link toolbox does not use a full internal precision as before. Thus it achieves speed up than the previous versions. However this cutting corner doesn't do a correct job for my problem, in which I have to use the ful...

I purchased Maple toolbox for Matlab. I assumed that I can run any maple command in Matlab, until I tried "seq". Is there any way to run [>seq(a[i],i=1..n); in Matlab using the maple toolbox?

I have Matlab 2010a(64bit) and Maple 15(think 64bit, not sure). When I setup the matlab toolbox, it installs the 32 bit toolbox with maplemex.mex32 file.

I am trying to load a very large database into matlab using the database toolbox. When I load it in using the visual Query Builder it is no problem. However when I try to do the same thing using code I recieve the following error message. ???

I have been searching around and can find no reason why this should be the case. Thank you If you are on Windows, I would suggest trying to use ADO via the actxserver function to query your database.

You're going to need to either contact the author of the toolbox for assistance: http://www.mathworks.com/matlabcentral/fileexchange/26523 or provide a LOT more information about what exactly "is NOT working properly" means before anyone on the group would have enough knowledge to understand what's gone wrong and h...

Hi, usually I work with Matlab but sometimes I prefer to use Maple. Often I end up copying lists of coefficients from Maple into Matlab almost by hand which is not efficient. Here's an example: B:=n->1/2*(-1)^n*(2*n+1)/n*2^(2*n)*bernoulli(2*n)/factorial(2*n); Then I use c=seq(B(n),n=1..20); cc=evalf(c); Then I copy the numbers (using my Windows copy and paste features). Is there a more efficient way? Usually I have to make some corrections, that is 10^-10 into e-10, etc. Any suggestions? Sorry for asking, such an elemantary question, but I am happy to help with issues in Matlab, too.

The 2nd column and the 4th column is the y axis data points and time data points respectively. The method i did was to do a loop to get the index that represents the max peak value. The problem is that i am umsure how to start another loop counter from the last index value that is achieved from the looping that i have used earllier. Here is the codes.
