I have many structure files (.mat) as output, whose size is around 1.9 GB each. Is there any way , by which i can save this structure file in low size or space format.
Or is there any way by which I can reduce the size of this structure file, so that it takes less space on my pc.

A first-pass estimate of the storage requirements would be:
800 fields times 400 times 15 cells per field times Q doubles per cell times 8 bytes per double
which is (Q * 38.4) megabytes where Q is the average number of doubles per cell (you did not give us an estimate of that value)
You ask about fitting that into "kilobytes". For the purpose of discussion, I will take that as meaning you would like to have at most 500 kilobytes of storage, as after that one would round up to speak in terms of megabytes instead of kilobytes.
>> syms Q; double(solve(1000*(500*1000) = 38400000*Q))
13.02
so if there is an average of less than 13 doubles per cell, the storage requirements could potentially be "kilobytes".
If your cells average more than 13 doubles per cell, it would be necessary to use compression techniques.
There would be overhead in marking the boundaries of which part of memory goes with which cell, so you would not be able to achieve as small as Q*38.4 megabytes with varying length arrays; the amount of overhead would depend upon the maximum length of each array.

Try to save it in different Mat-formats:
data = load('YourFile.mat');
save('test1.mat', '-v6')
save('test2.mat', '-v7')
save('test3.mat', '-v7.3')
Is one of them significantly smaller?
Do you store large integer arrays in the type double? Then a conversion can reduce the memory.
