Hi all :

This is my code :

for i=1:3689 b=bret(1,10000*q(i,1)-9999:10000*q(i,1)) sel=(max(b)-min(b))/3.3 y=peakfinder(b,sel) p=size(y,2) for j=1:p-1 v(1,j)=((y(1,j+1)-y(1,j))) end; * SYNTAX REQUIRED * end;

In the above loop, I get arrays of random size for the value V. I want all these arrays to be stored in one single array. To pre allocate memory, I donot know the size of the arrays which are being generated. Kindly Help.!

Please edit your question and use the {} Code button above the text box to format your code, and make it more readable.

Note you should not use i as your loop variable, as this is the name of the inbuilt function for the imaginary unit .

在 MATLAB Online 中打开

You can use cell arrays to store variables of different sizes. Like

V{i}(j)= y(j+1) - y(j);

And something is probably wrong with your code, since the inner loop does not depend on i.

Inner loop doesn't rely on value of 'I'. It depends on the size of 'P'. I want to store the values i get in the inner loop into an array continuously. The above code didn't work.
