I have .mat file in workspace which is 5120x1 dimention. I want to split that into (1024x1), (2048x1), (3072x1), (4096x1) and (5120x1) in 5 different varibales.
Is it possible with mat2cell function?

You haven’t told us what classes they are and haven’t shared the file either.

You can't have a file in your workspace, only variables (and objects if you don't count those as variables).
There are some guesses involved in what you want. Below is my best guess.
data=rand(5120,1);%generate some random data
c=num2cell(1024:1024:5120);
for n=1:numel(c)
c{n}=data(1:c{n});
end
c
You shouldn't want to put it in seperately named variables, as that will prevent you from using indexing to get to these results. However, if you insist, you can use the deal function to split the cell.
[foo,bar,foobar,f00,barr]=deal(c{:});
foo

for n=1:numel(c)
data=c{n};
filename=sprintf('data_part_%02d.mat',n);
save(filename,'data')
end
This will write the 50 mat files you appear to want.
You still haven't explained how the input to your later function works. We might be able to suggest improvements.
