It depends on what you want to do with the data. It is possible that there are other solutions that achieve what you want without going through the trouble of programming in Matlab.
#Ravi_teja sir thank you, I am working to develop a software which will automatic detect glaucoma from 3d oct images, but dont know how could i program it ? load the 3d image and its processing. do you have any idea which tool will be better rather than matlab.
R can also often be used as an alternative, it is opensource and has a lot of contributors around the globe. Maybe somebody has already done some programming to analyse OCT 3D images or similar images.
