I have a for loop. In this loop I have a function with 3 returning arguments

Now I should save the content of this returning variables. The content is a 10*100 uint16 matrix.

number = {'test1' ,'text2', 'text3'}        %A array with content
for i = 1: length(number)                   %Do something for every array element in number
    [val1, val2, val3] = dosthg(number{i})      %function returns a 10*100 uint16matrix
    
        %how to save the return values? 
        pos1(i) = val1;      pos2(i) = val2;      pos3(i) = val3;
        %try 2
        pos1 = [{pos1} {val1}];
    plot(time,mean(pos1(i)));
    hold on;
    
end

At the end all for iterations shoud draw a new line in a pot.

Now my problem is, how can I add the new data to the Array/Cell?

Thanks for your answer

在 MATLAB Online 中打开

number = {'test1' ,'text2', 'text3'}        %A array with content
num_num = length(number);
pos1 = cell(num_num, 1);
pos2 = cell(num_num, 1);
pos3 = cell(num_num, 1);
for i = 1: num_num                   %Do something for every array element in number
    [val1, val2, val3] = dosthg(number{i})      %function returns a 10*100 uint16matrix
    
    pos1{i} = val1;
    pos2{i} = val2;
    pos3{i} = val3;
    plot(time,mean(val1));
    hold on;
end
