opendx with matlab 05/17/11 at 02:13:03     I use "dx -builder" to make a new module ,named matlab .In this new module,I try to call matlab to draw some pictures .In matlab.make file,I add " -I /usr/local/matlab/extern/include/  -L /usr/local/matlab/bin/glnx86/ -leng " ,so that module can compile successfully . I can use the module in opendx without any problem .But in the  webdx,  there is  a problem when I use this module . Error is that : MDF file:Invalid data:cannot load file 'matlab',libeng.so:cannot open shared object file:No such file or directory /module matlab     ,I don't know why I can use the module in opendx ,but in webdx there is a problem .      Joelr ,do you have any ideas ?

Re: opendx with matlab Reply #1 - 05/17/11 at 03:55:25   First thing is to make sure it's finding your MDF file ok when running webdx. In the config xml file for your app, add the following property:   <property              name="mdf"            type="cmd-arg"            value="-mdf FILE" />   where FILE is the full path to your .mdf file.     If you still have problems, in your mdf, try giving the complete path to your .so file.   Joel
