Question

0 个投票

Is there any way to reduce writing each time by any means..

y = cat(3, x{1,1}, x{1,2}, x{1,3}, x{1,4},...
    x{1,5}, x{1,6}, x{1,7}, x{1,8}, x{1,9},...
    x{1,10}, x{1,11}, x{1,12});

the command like

for i = 1:12
    y = cat(3, x{1,i});
end

does not work.

Hi, play some trick will do.

x{1,1} = [1 1 3; 4 5 6];
x{1,2} = [1 2 3; 5 6 7];
x{1,3} = [1 2 3; 4 5 6];
y1 =[];
for i = 1:1:length(x)
    y1 = cat(3,y1,cat(3,x{1,i})); 
end

See the "How to Use the Comma-Separated List" section on this documentation page.
