Read fortran file matlab

A similar data file from C flat binary file is attached to this solution. Below is the code that was used to generate the binary data file. Here is the C code that was used to generate the flat binary data file:.

Accepted Answer. MathWorks Support Team on 25 Mar Vote 3. Cancel Copy to Clipboard. Thus, the code above has 3 records.

The record length information is tagged on at the beginning and end of each record. This is the record length in hex, i.

Counting 72 bytes from that point is another " " which is followed by " c" this is the length of the next record, i. The extraneous characters must either be filtered out or stripped off. Stripping them off would require writing C code. You will have to modify your MATLAb file to read out the record length information and access the data in which you are interested. Here is an example file that does so:. Here is the output:. Since Digitial Fortran writes two unsigned characters as the start tag and has no end tag, you need code such as that below in order to read a binary file produced by Digital Fortran code:.

You can view bytes from bytevec as unsigned integers from 0 to You sholud define i1 , i2 variables as start and end byte positions excluding header with fixed length, if you know binary structure of your file. It means that you should know needed byte positions. When you call typecast , it will reduce size of input vector by 4 from 1-byte as uint8 to 4-byte as float.
