I have a cell array 1x7 and every matrix contains 5844x4double and they're all same size. Now i need to extract data from each cell array and each matrixe(5844x4double ) and the create other matrix containing the data from each cell array and each matrixe(5844x4double ). how can i do that ?
for i=1:length(cellarrray)
for j = 1:5844
dy_strfr1= rfdata_tsstrfr1{1,i}(1:j,4)
elv_strfr1= ellnlt_stallrfr1{1,i}(1:j,1)
lon_strfr1= ellnlt_stallrfr1{1,i}(1:j,2)
lat_strfr1= ellnlt_stallrfr1{1,i}(1:j,3)
end
end

"how can I attached the mat data?"
Save all relevant variables in one mat file. Then click the paperclip button in your answer/comment to upload it.

how can I attached the mat data?
just right click on the mat file > save as > put any name.
here I have tried to make a cell array with random data.
a=randi(100,5844,4);
b=randi(200,5844,4);
c=randi(300,5844,4);
d=randi(400,5844,4);
e=randi(500,5844,4);
f=randi(600,5844,4);
g=randi(700,5844,4);
A={a;b;c;d;e;f;g}; % A is your cell array
B=[A{:}];
% expected variable
i1=B(:,1:4);
i2=B(:,5:8);
i3=B(:,9:12);
i4=B(:,13:16);
i5=B(:,17:20);
i6=B(:,21:24);
i7=B(:,25:28);

try this:
AA=A.rfdata_tsstrfr1 ;
rfdata=[AA{:}];
i1=rfdata(:,1:4);
i2=rfdata(:,5:8);
i3=rfdata(:,9:12);
i4=rfdata(:,13:16);
i5=rfdata(:,17:20);
i6=rfdata(:,21:24);
i7=rfdata(:,25:28);
BB=B.ellnlt_stallrfr1;
stallrfr=[BB{:}];
x1=stallrfr(:,1:3);
x2=stallrfr(:,4:6);
x3=stallrfr(:,7:9);
x4=stallrfr(:,10:12);
x5=stallrfr(:,13:15);
x6=stallrfr(:,16:18);
x7=stallrfr(:,19:21);
