After lots of hunting around with old friends, I was able to locate Windows libraries of Matlab 6.5. In addition, I have put a couple "extras" into the load5 command. As soon as it appears in the file exchange (and i notice it), i will update the file to a .zip file which will contain both Windows and Linux versions of load5. Note that if you use this MEX file with R14 in linux, you will need to copy the libz.so.1.2.2 to either the matlab directory and modify the symbolic links libz.so and libz.so.1, or put it in your path and make sure the LD_LIBRARY_PATH has your directory prece...

hi, i want to upgrade my Matlab 6.5 to Matlab7, will it cause any effects to the M-files that i saved before?

Hi, I,ve found the reason for a problem I had (and posted last week), passing from M 5.3 to 6.

The field being assigned to is referenced in the assignment using an array index. For example, mystruct.emptyfield = []; mystruct.emptyfield(1) = struct('f1', 25); ???

Hi all! Please help me get a clearer picture of what i have read so far... I'm into a project which requires the usage of Matlab computation and i have a program in VC++.. I want my VC++ program to run and use the *.m files without the running of Matlab. In addition, i already written the .m files in Matlab. I have set up my env with mbuild -setup. here's my questions: is [mcc] used to convert .m to .c? (eg. mcc -e bp_meter.m bp_detect.m) can the convert .c files be imported into my VC++ project and compiled into stand alone application without the need to run Matlab? what is th...

I am looking for information here on the MathWorks website about the changes between MATLAB 6 and MATLAB 7. Specifically, I am looking for information about changes in the handling of .mat files. For example if I have a mat-file: example.mat located in the MATLAB current directory. In MATLAB 7 I can load this data-file into the MATLAB workspace with: >> load example And it loads fine. If I type the above load command in MATLAB 6 I get and error. Is there anything that provides the technical information for this? Thanks Dave Dave wrote: > I am looking for information here on t...

Hello, I followed the instrutions on http://www.mathworks.com/support/solutions/en/data/1-1Y1FEG/index.html?solution=1-1Y1FEG to debug my mex file in Microsoft Visual ++ 6.0 .

However, I get the following error messages in Visual and if I call the mex function from Matlab it does not stop at the breakpoint that I have set in Visual. It just runs over it.

Hi guys, I have been creating dll using the mex command on Compaq Visual Fortran 6.6 under WinXP. My fortran programs require the use of DGEMM, and in the past I have been linking to the LAPACK using libdflapck.dll without any issue. When 7.0/7.0.1 arrive, they forgot to include libdflapack.dll, so I went back to use the one from version 6.5.1. Unfortunately, there is some incompatibility with the old version of libdflapack.dll and Matlab 7.0/7.0.1. The mex created dll just fails to run. It is a platform dependent problem. On some machines (P3, AMD XP), the dll runs without problem. On faster machines like P4, Centrino, AMD64, I get an "invalid MEX file" message. I sent TMW technical support this question a while ago. Besides acknowledging the problem and telling me that there is no workaround, there is practically no help. I wonder if anyone has come across this problem and has found any solution. I was able to use another BLAS and ATLAS library found on the web instead of libdflapack.dll and mex the Fortran file without any problem, but these libraries are very old and not optimized for my machine, so the performance is much worse than the one from using the libdflapack.dll. I was also able to use CXML from CVF, but again the performance is much worse. My questions are: 1. Anyway to change the mex script to make the libdflapack.dll work? 2. Anyway to create an Atlas library of LAPack and BLAS that works with Compaq Visual Fortran (in particular...

Hi, I've just installed Matlab 7 and it's incredibly slow when starting up and also when closing. Once the Matlab program window opens, it looks like as if it has started but it says "Initilizing..." in the Status bar at the bottom and the Start button is disabled. Basically you can't do anything. I never had such problems with Matlab 6. Don't have any virus program running either. Is there any setting I need to adjust to prevent this from happening? Cos it takes nearly 2-3 mins just to complete initialization!! I tried installing it on two notebooks and they both ...

Hi there I want to save my data into data file in Matlab v7 (R14). How can I save it in a manner such that it is also loadable in Matlab v6.5 (R13) ?

I have a fortran file which I've been mex compiling using Compaq VF 6.5 under Matlab 6.5.1, and it works fine. I just upgraded to CVF 6.6 (using the free 6.5->6.6 upgrade from Compaq's webpage), and discovered that my file will no longer compile properly. To be specific, it compiles/links fine, but when I try to run I get: Unable to load mex file: <my extension>myfile.dll The specified procedure could not be found When I dug a little deeper, it seems that this only happens on files that use dynamically allocated memory. In particular, when I compared the two different .dll&#...
