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

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

thanks for your answer.
The content of number = {...} is changing because the user puts more ore less content in the array. How should I solve this?

The line of code I posted,
num_num = length(number);
asks how much content the user entered into the array. Then I use that amount to allocate the variables and to control the looping.
In other words, the code already takes care of that.
