How to Read Fortran 90 Unformatted Binary Files into Matlab

9 views (last 30 days)
Is it even possible to read unformatted binary files created by fortran 90 (on Linux) into Matlab running on Windows? These binary files do not even have any extension.
Please, help me so that I can crack into the files.

Possible, yes...but you'll have to know the record length and how the given compiler writes the internal structure to do so.
I would recommend rather than using 'UNFORMATTED' to create the files as stream files. Depending on the compiler and age thereof, the way to do this may be by using an extension ('BINARY' is one fairly common one) although it has now been standardized by later Standards and the commonly-available compilers all now support writing stream files in a Standard manner.
If you do this, fread will be all you'll need with the matching precision and endian-ness taken care of in fopen and the conversion specification.
