Hello , anybody knows when I execute the function "regress" to this model (STAR(1)) Yt = 1 - 0-5Yt-1 - (4 + 0.4Yt-1)G(gamma*Yt-1) + et, where G(z) =1/ [1 + exp(-z)], gamma=4; et=N(0,1) I obtain different radically different results from matlab 6.5 to matlab 7.0 that with other models??Any suggestion to avoid this problem???

Please show the relevant code. Hope this helps. Greg Well,I have made several tests and this is the result: -When I use the function regress in this format in matlab 6.5, it works: [B1,BINT1,R_X,RINT1,STATS1]=regress(X(2:length(X))',[ones(length(X)-1,1),X(1:length(X)-1)']); -When I use the same format in matlab 7.0 it doesn't works, but if I use this format: [B1,BINT1,R_X,RINT1,STATS1]=regress(X(2:length(X))',X(1:length(X)-1)'); It works in matlab 7.0. Then I think the problem is how the function regress treats the independent term in both versions?? regards Greg Heath <heath@alumni.brown.edu> wrote in message <69879944-34b7-4262-a193-0bb545d8cf99@...

Hello all, I would like to spawn multiple matlab processes from an '.m' script. Meaning, run an m-file from a 'parent' Matlab that launches, say, 8 more 'children' matlab processes. I'd like to do it in such a way that the same m-file in the 'parent' is able to close down, or kill, all the 'children' processes. Any suggestions? Joe ...

Hello All, I'm working with an aplication that use the matlab engine.

I downloaded the MS visual C++ 2008 Express Edition and the SDK as detailed in http://www.mathworks.com/support/solutions/en/data/1-6IJJ3L/?solution=1-6IJJ3L My embedded function didnt work at the beginning because I did "mex -setup" before I installed my SDK. But after I installed the SDK, I ran "mex -setup" in Matlab once again and choose the MS visual C++2008 as my compiler. Then, my embedded matlab function worked. Thanks to the contribution from above! ...

Hi, is it possible to create dll in Matlab and then using it in other Matlab apllication? I've made a simple function and put it into dll. But when I try to use this library in other apllication written in matlab it doesn't works.

After that, my phone can download the result. The key part is that can I use PHP to call matlab function? Or any mechanism I can use to call Matlab through server-end script? My server will be the local hosted server on Mac computer. Also, Matlab is installed on my mac too. Thanks you very much.

My problem with matlab script node is related to calling function in matlab. I created an m-file function that takes an imput temperature (from DAQ) and defines a material property. My matlab script node doesn't seem to recognize my function. I have placed the function in the folder the vi is currently located, but it doesn't read it. How do I get matlab script node to read the functions I create in matlab? Add the directory to matlab path, or call the .m file with it full name ( D:\..... \myfile.m) Let me clarify, I have pasted my matlab code into the matlab scrip node. In this code, I have called a subfunction that I have created. Example k(n)=k_c(T(n)) where k_c is a subfunction I have created. How do I get my code in the node to sucessfully read the subfunction k_c? As indicated, you need to add the directory where the .m file containing the function resides to the list of paths that are read in. This is your startup.m file. The other option is to do a "cd" command prior to calling your function to change to the directory where the .m file containing the function resides. Thanks for reiterating the information. My matlab script node is working properly. I had never used the "cd" command in matlab. I always set the working directory when I open the program, and put all the m files into t...
