"How do I write the h5 file data in exactly the same way as it was written in original binary file written by Fortran?"
It is writing the file the same, the problem is that fortran stores arrays in column major, and C in row major order. You state "it automatically transposes the matrix" - not true - it transposes the dimensions so that the data is still stored the same, but when you write array[z,y,x] from fortran, you want to read it as array[x,y,z] from C. The actual data on disk is the same as your binary fortran data, but the dimensions are reversed compared to the same data from C. Does that help? - the short answer is just swap the order of the dimensions in your read function in the C version and then things should appear the same. (but you must declare your arrays with the dimensions flipped). If you want to actually transpose the data, then I'm sure google will provide a code snippet I hope I'm not remembering this wrong.

Apparently, this is because HDF5 uses the C convention for writing binary files, as explained in section: 7.3.2.5. of this page.<http://www.hdfgroup.org/HDF5/doc/UG/UG_frame12Dataspaces.html> Is anyone aware of this situation? And any solutions for this problem? How do I write the h5 file data in exactly the same way as it was written in original binary file written by Fortran?
