I have a satellite data values stored in a .dat file of almost 900 MB. The data is in the form of int8. I want to read as much data as possible from the start and then pass it in a function argument and then save the new signal in a separate file. I have used importdata but it cant work and unable to read large data file. Is there any other way which I can use to read data in chunks and put them together afterwards? Anyone please help me out. Its very important that I read this data.
The specifications of software, platform & PC are:
Matlab R2015a. Windows 7 64-bit, Core i5 1st Gen., 4 GB RAM, 250 of hard Disk Space

The data is in the form of int8
What does that mean? Is the file a text file (as Bob assumed) or a binary file. Loading a 900MB binary file shouldn't take long.

"have to upload y file in a function argument"
And what does that mean?
You have a large file; TMW supplies several tools to deal with those but to give any specific help we need at least a klew as to what it is that is the real problem, also specifically.
