HELP needed in importing and working on an ascii text file!!

[1vignesh1]

Hello there!

I have an ascii text file containing data of Intensity data matrix and phase data matrix of a surface profile obtained using an interferometer (Zygo interferometer and the software that generated the profile plot was MetroPro).

Now I need to work on this data in matlab.

I have attached the text file that carries the data.

I'm completely a fresher to this software and quite struggling to import this data into matlab and work on it.

Please if somebody can guide me, it will be a lot more helpful for my dissertation.

Note: In the attached text file, initial 15 lines are the header lines. The numeric data from between the first and the second "#" symbol signifies the intensity data matrix an the data from the second "#" symbol to the end of the file represents the Phase data matrix.

Thanks in advance for the help.

Pls let me know for more details!

type "uiimport" and press return. Viola!

By the way, I'd forgotten how to do this, so I typed "help import" to remind myself. Something to try next time.

Or "voilà!", for those celebrating without musical instruments.

Another option is the DLMREAD command. It works well, and doesn't require any clicking when you run your script.

Handy hint, in the uiimport gui there is an option to save the equivalent m code, so you can cut and paste that into your own m files.
