cell_of_doubles.mat

Hi,

I have the cell of doubles array "cell_of_doubles" with 19 columns (19 cells). I am looking to extract only the first three columns from each cell and save them seperately in a three column vector (not a cell array).

This way I would like to create 19 new variables each containing three columns.

How would I do that?

Thank you!

在 MATLAB Online 中打开

A=load('cell_of_doubles.mat');
B=A.cell_of_double_balls  ;
C=cell(size(B,2),1);
for i=1:size(B,2)
    C{i}=B{1, i}(:,1:3);  % first 3 columns from every cell
end
firstcell=C{1, 1};  % extract variable 1 by linear indexing
secondcell=C{2, 1}; % extract variable 2 by linear indexing and so on....
