Hello Friends, I have Matlab R2008. Here-uin I am trying out some XML read/writes(xmlread specifically). FOr that I just pasted the code in the help files viz - xDoc = xmlread(fullfile(matlabroot, ... 'toolbox/matlab/general/info.xml')); xRoot = xDoc.getDocumentElement; Pls note that the windows I am using is the Korean version of Windows. But, I have sorted all path issues in the classpth.txt and librarypath.txt for the toolboxes and stuff. Now, when the above mentioned instructions were typed in the command window I get the following error - ???

Hi all, I'm building a java swing based GUI for my Matlab application. As such, user input is available as text strings, for example "{[0; 0], [3.5 0; 0 2]}" (mean vector and covariance matrix of a 2D Gaussian). The user input will be passed to the compiled matlab method as a MWCellArray. Problem is how do a convert (parse) the above string into a MWCellArray? From its javadoc http://www.mathworks.com/access/helpdesk/help/toolbox/javabuilder/MWArrayAPI/index.html the following method is available: java.lang.String toString() Returns a string representation of this array, but the reverse method is not. Evidently, parsing a string like the one above is a non trivial task and I'm loath to attempt writing one by myself. I would be very thankful if someone can point me to the required parser implementation. Matlab itself is carrying out this task all the time, perhaps it is possible to access Matlab's own parser. Help much appreciated, Ritesh ...

Dear All I hope that you are doing well and everything is OK. I have a question, please: I have a decimal number stored in a matrix. For example, Matrix subscripts: 1 2 3 5 6 7 8 9 10 Values: 8 9 8 7 7 9 9 2 7 So, the number is: 898779927 My matrix consists of 3000 cells and each cell contains a number from 0-9. I need to get the number of bits for this string in binary. However, I cannot convert it to binary as the program will give me out of range. Thanks and your response will be much appreciated.

I don't ordinarily do other's homework, but in the spirit of the season, I'll meet you more than half way. If you get "Out of range", then you're converting the wrong item. The correct answer is 30.

greeting all, i'm using nonlcon(nonlinear inequality constraint) with GA from the toolbox provided by matlab. does anyone notice the extreme slowlness in evaluating nonlinear constraint as compared to other linear constraint? my problem for nonlinear constraint is as follow c(1)=x+y^2-2*ones(N,1) where x and y are Nx1 vector. which means if N increases, the size of constraint increases. and to clarify, the min problem is sometime like min c'z where z=[x;y], which means x and y are some range of variable within z(just a matter of problem formulation) well, is there anyone with other alternative or is it possible or method in including non-linear constraint directly to fitness function? (well, actually nonlcon deals nonlinear constraint by using Augmented Lagrangian Pattern Search from what i see from the help file, or am i wrong?) and one more question, is there anyone that attempt to attempt to apply mixed integer problem into the GA in matlab? For now, i can only switch before pure integer or pure real number problem, but not mixed at the moment. I will be trying to add in some repair operator to fix up the variable that needs to be integer and other remaining in real number. I'm not sure why you are using ga to solve your problem. Did you find fmincon unsatisfactory in any way?

Make sure that the line terminator is the same on both sides, and make sure that the other side is really sending the line terminator, and make sure that the other side is flushing its buffer after constructing the character string to send. On unix-type systems, the line terminator is alway just the newline character (control-J, character value decimal 10). On Windows systems when the object is open in binary mode, the line terminator is the newline character like above. On Windows systems when the object is open in text mode, the line terminator is the character pair of newline followed by carriage return, decimal 10 then decimal 13. With regards to flushing the buffer: either the other end has to be sending without any buffering at all (e.g., have opened the port using the C open() call instead of fopen(), and sends characters using putchar() or putc(), instead of fputs() or fwrite); if the other end is using bufferin...
