How can I write a text file using java in a way Matlab understands the text file on import ?

The Text file contains mapping information between two variables, data type of each of the variables etc. The information to be written to the text file is extracted from database. How can I write this information to the text file using java so that Matlab understands the text file on import and produces .mat file from my input text file.

Any help would be appreciated. Thanks !!

MATLAB can read any text file, but some formats are easier to parse than others.

With the variety of information you have and the fact you have different data types, you might want to consider writing XML in Java and then using xmlread() in MATLAB.

Thanks for your reply !!

Agreed. In that case the XML file that I write in java. How do I import this file onto my matlab using java from eclipse ?

Despite of the fact that XML would be efficient way , Is it still possible that I implement it using text files ? (Yes/No)

xmlread()

If you look inside the code for xmlread() you will see that it can take a couple of different kinds of java objects in addition to a plain file name. It ends up invoking java methods to do the XML parsing.

Yes, it is possible to implement an information transfer using plain text files. We would need a sample file or two in order to tell you the better ways to parse it.
