I have code that uses signalblks.MultimediaFileReader and/or signalblks.MultimediaFileWriter System Objects which works fine in R2010a. When I upgraded to R2010b, I received warnings that the name has been changed. However, when I replaced calls to signalblks.MultimediaFileReader and/or signalblks.MultimediaFileWriter with calls to dsp.AudioFileReader and dsp.AudioFileWriter respectively, I received some cryptic error messages.
For example, when I executed the following code:
h = dsp.AudioFileReader;close(h)
I received the following error message:
??? Error using ==> horzcat System objects do not support concatenation. Error in ==> close at 67 h = [h cur_arg]; %#ok
