dividing a bigger array into sub-arrays and saving them as array-element

Question

0 个投票

Hi all, a small problem.

I have data, around 100,000x1 stored in an array. I want to split this bigger array into smaller arrays(not of same size). The number of sub-arrays is also not same (28, 30, 33 etc etc.). I will find different parameters from each sub-array and will save the results in excel file.

How can i save an array as element of array? I tried following code but it didn't worked.

cl1 = fdampl(1:1400);
cl2 = fdampl(2660:3720);
cl = zeros(30,1);       %initialize the array
cl(1)= cl1;
cl(2)= cl2;
subplot (2,1,1);plot(cl(1))
subplot (2,1,2);plot(cl(2))

instead of "zeros" to initialize matrix, i also tried "cell" but it didn't worked either.

any help will be welcomed.

Are the number of parameters calculated for each sub-array the same?

You could use a cell array:

cl  = cell(30,1);       %initialize the array
cl{1} = cl1;
cl{2} = cl2;
etc.

Note that cell arrays use two different kinds of indexing, you need to know the difference:

That's cool. After I will get the array of arrays, i will apply 4 different fornmuale on each sub-array and then save the output. inside loop, i have to use

for i=1:3
  a = cl{i}
  plot(a);
etc. etc.
end

here i need to put {} curly brackets instead of ().

Thanks Stephen, really appreciated.
