Segmentation Violation Error while loading a .mat file in MATLAB 7.3.0 (R2006b)

Hello,

I am having a problem while loading a .mat file in my Matlab console. It gives a segmentation violation error and creates a crash report. I sent this crash report also to the email mentioned in the crash report , but there is no reply till now and it is already 2 weeks. I am desperate to get out of this as the deadline for my work is approaching and I am stuck in to something which is out of my comprehension. Here is what it generates:

You should probably open a support case.

Answer 1

[Walter Roberson]

I see you are running R2006b, but which MATLAB was the .mat file created with? If the .mat file was created with a MATLAB version that supported the new "classdef" OOP style and the file contains an instance of one of those classes, then your R2006b MATLAB would probably crash in trying to open the file.

As best I recall, there is no work-around for this particular issue for R2006b (but I seem to recall that there was a patch for the MATLAB version that immediately proceeded the introduction of the new objects.)

[Irfan]

Thanks a lot for the reply.

What do you mean by opening a support case?

Which patch you are talking about, is it available online?? Does it cost something?
