Can I use 'fopen' to open a file with VAX machine format in MATLAB 2015a?

I’m trying to run an old script, am I’m getting an error on the following line of code:

fopen(FullFileName,'r','d'); % DEC VAX D floating point and VAX ordering

I think it’s the 'd' input that’s causing a problem, and the error is that this is an invalid machine format.

Google tells me that 'd' once was an option for machine format, but it is not one of the options listed in the help document for fopen in MATLAB 2015a (where the options are 'n' or 'native', 'b' or 'ieee-be', 'l' or 'ieee-le', 's' or 'ieee-be.l64', and 'a' or 'ieee-le.l64').

So could this be a version issue? Does anyone know how I can open files with VAX D floating point and VAX ordering in Matlab 2015a?

Thanks very much

I've tried this one, but didn't work on my case, do you guys find any other solutions?

Please explain "didn't work" with any details.

Matlab has dropped the VAX formats in R2008b, unfortuantely. It has vanished without a message in the change notes.

Then what should we do?

You have to convert the files or use an old version of Matlab.
