Hello
I am new to matlab. I am processing the strong motion data(earthquake record) from data base. I have to process hundreds of data. I have to do the same operation for those hundreds of data. 
I am able to load the file individually. I would like to know how can i load all the files automatically and get the result for individual records.

Thanks

Look at ML wiki FAQ -- http://matlabwiki.mathworks.com/MATLAB_FAQ

I forget the FAQ # but it's pretty close to the top...

You could try using MAGIC - I built it for this sort of thing.  Just insert your custom code into the function AnalyzeSingleImage(), and the GUI, the listing of data files, the batch processing, writing to Excel, displaying the data (images but could easily be converted to plots), etc. are all done for you.

This GUI will help the novice user get up to speed very quickly on using GUI-based applications. Everything is laid out in a very simple Step 1, Step 2, Step 3, etc. layout. It is a very good starting point for a typical image analysis application. This application uses GUIDE to do the user interface design, and has most of the basic controls such as buttons, listboxes, checkboxes, radio buttons, scrollbars, etc. It allows the user to select a folder of images, select one or more images and display them, to select a series of options, and to individually or batch process one or more images. The user can optionally apply a mask (region of interest) to the image so that only the area within the mask will be analyzed. The results are optionally sent to Excel. In this demo, I do some very basic particle sizing but in use, the user would replace that simple demo code in the function 
AnalyzeSingleImage() with their own code. Works with Windows or Unix since paths are all forward slashes. Requires the Image Processing Toolbox to do the simple particle sizing demo, but if you delete that demo code before using it, then the IP toolbox would not be required and it would still demonstrate the basic GUI-based file processing functionality.
