I am a beginner in the field of Data Mining. I have a data which i need to process before visualizing any useful results. So I do the following:

  1. Preprocess data using Java Program ( Output : txt files) (Input: FileNames)
  2. Convert .txt files to .xls files ( Excel file)
  3. Import excel file in MATLAB
  4. Write Matlab Script to draw some plots on the imported data

I wish to automate this process by just pressing run button and then it happens automatically.

Please guide me how to integrate my work so instead of doing these 4 steps each time i just provide input file names and all the work is done in one go.

Thanks!

    You can use arbitrary Java classes from within MATLAB – it is supported to run user-defined classes and even pass data between them and MATLAB. This would give you the following benefits:

    • no need to write text files/XLS and then import them into matlab
    • write everything in one MATLAB script – that is what duffymo had in mind, just that you do not need any shell/batch processing. Everything is done in MATLAB
    • you could add a MATLAB-implemented GUI to handle the process

    Have a look at this SO post for some insights.
