I cannot load a variable (info.mat) file with size 973 MB. It shows

Error using load
Out of memory. Type HELP MEMORY for your options. 

Can Anyone suggest what to do?

It is possible to get into that situation in some cases:

file was built on a system with more memory and involves very heavy compression (for example an array that is nearly all zero would compress well)
file is corrupt
file was built incrementally, using -append to write one variable at a time, but you are trying to load back the entire file
variables were built incrementally using matfile() and a -v7.3 file, which can sometimes permit you to create a variable in a file that is larger than your available memory
certain cases involving symbolic expressions can end up expanding representation
If you accidentally saved a figure handle as part of data, then loading the figure could take a lot of memory

Did you do as suggested and actually check your memory?

>> memory

Memory available for all arrays:        2745 MB (2.878e+09 bytes) *

I also got the same error 'Out of memory. Type HELP MEMORY for your options.'. I closed all the other opened applications. It increaed the RAM availabe to Matlab. Then I ran the matlab code again. This time it ran smoothly. The dataset that i tried to load was about 605Mb.
