Hello, I have cell array of dimension 200*1 which contains information about an image. I want to store the data of a variable in the cell to a new variable. The cell is of type uint 8.

for example x = sensorscan{1,1}.data.sensor1; the above line stores the value of sensor1 in x.

But now I want that it should run for the entire cell array that is {200*1}. I have tried using for loop but it gives me an error. Regards

Do you think that if you shared the error message (all the red text in the command window) that someone might actually be able to suggest a solution?

在 MATLAB Online 中打开

my_cell = cell(10,1);
% write into a cell
for k=1:size(my_cell,1)
    my_cell{k,1} = rand;
end
% read the cell
for k = 1:size(my_cell,1)
    x = my_cell{1,1}
end

I realized I made a mistake: try this out

my_cell = cell(10,1);
% write into a cell
for k=1:size(my_cell,1)
    my_cell{k,1} = rand;
end
% read the cell
for k = 1:size(my_cell,1)
    x = my_cell{k,1}  % missing ";" to present the value of x on command window
end
