I have 1x25 cell array, which looks like this :
0.300000 0.410000 ,0.41000 0.430000 ,...
I want to get only first element from the first cell ( 0.300000 ) and put in a variable x, and second element from the first cell (0.410000) and put it into a variable y. How can I do it?

"I have 1x25 cell array, which looks like this :"
0.300000 0.410000 ,0.41000 0.430000 ,...
"if I do e.g"
x=C{1,1} %get the first element
"I still get both cell elements '0.300000 0.410000'"
Clearly, one of these statement contradict the other. My suspicion is that your cell array is:
C = {[0.3, 0.41], [0.41, 0.43], ...}
That is, each cell is a 1x2 matrix. To get the 1st element of the matrix in cell 1:
C{1}(1)
%or C{1, 1}(1) if you want to use 2D indexing for the cell array
%or C{1, 1}(1, 1) if you want to use 2D indexing for the matrix as well.
C{1} only gives you the content of the cell, which is a matrix. To access the matrix elements, you use standard () indexing.

Thank you so much, this really helped. I actually have cell array where each cell is a 1x2 matrix.

Hello Lara,
You can do something like
C = { 0.300000 0.410000 ,0.41000 0.430000 }; % your Cell
x=C{1,1} % extracting first element
y=C{1,2} % extracting second element
z=C{1,3} % extracting first element
you can write a simple loop to extract all data at once, if you have very large data.

How do I extract first two elements, or the second and third at the same time?
