Mat File With Header

However v5 v6 and v7 refer to different capabilities on the same format.

Mat file with header.

I have a question on how i can add headers to a data matrix. What i ve done is created a 5x3 data matrix that i m wanting to be able to go back and add headers to. If we try saving with the v6 flag we get a mat file with a header reporting matlab 5 0 mat file as shown in the example code below. It s been a while now that matlab has switched the default over to the newer 7 x mat file format which is completely different based on hdf and completely undocumented.

Each array is a data element as are some other matlab constructs. Mat file header level 5 mat files begin with a 128 byte header made up of a 124 byte text field and two 16 bit flag fields author. The mat 5 format stores all data fields with a header tag that contains the number of bytes and how they should be interpreted. Mat file header level 5 mat files begin with a 128 byte header made up of a 124 byte text field and two 16 bit flag fields author.

Ok you could theoretically store some limited metadata in the header of a version 5 mat file. If you are trying to save to a text file with column headers then really the best way is to fopen fprintf the headers fprintf the data and then fclose. This use of the term element should not be confused with the way the term is used in xml based format specifications. The numeric data in a line is separated by a.

The format in which the mat files are saved is officially known as level 5 format. Once you had created the table described there you can save it to a mat file. This format probably also has a way to embed some metadata. Level 5 mat files are made up of a 128 byte header followed by one or more data elements.

I m new to matlab so i m not sure if i need to use the fprint function or if i need to change from csv to another format to make this easier. Are you trying to create a text output file or a binary output file.
