Dear Navan,
You could have a look at this documentation website of Mathworks, where many examples can be found to upload large data files. One of the functions is " datastore" which is may be a good use for you.
Good luck! Christiaan

I am working with 2014 b version of matlab and now i could use the function datastore. i could access to file but i could not find out my big data.
As i have shown in 2 red circles 1) i am expecting a double numberic array of 50000*100 matrix like the small red circle 2) By using the code datastore ds=datastore('D:\nnn.txt'); i am getting many files that are there in the bigger red circle. But no files for 50000*100 matrix.
Pls help
