How to generate data using for loop and save in rows in MATLAB

Hello every one i hope you are doing well.

I have the following code which generate data.

i want it to run for 100 times and saves results in rows

like loop is 100 and output should be 100 rows

Repeat=randi([1 1000], 1, 5);
prf=randi([1 1000], 1,5);
DS =repelem(prf,Repeat);
scatter(1:length(DS(1,:)),DS(1,:))

Something like this?

clear,clc

Repeat=randi([1 1000], 1, 10);

for i=1:200
    prf=randi([1 1000], 1,10);
    DS(i,:) =repelem(prf,Repeat);
    plot(1:size(DS,2),DS(i,:))
    hold on
end

@Davide Masiello

i do that but it not working

for i=1:200
    Repeat=randi([1 1000], 1, 10);
    prf=randi([1 1000], 1,10);
    DS(i,:) =repelem(prf,Repeat);
    scatter(1:length(DS(1,:)),DS(1,:))
end

The problem is that Repeat is generated by a randi function, which means that the size of

repelem(prf,Repeat)

changes at every iteration of the loop.

In order to fill up DS, you must have the same row length at each iteration.

@Davide Masiello then how can i do that?

[Davide Masiello]

It depends on what you need.

Why do you use repelem?

[Med Future]

@Davide Masiello repelem is used to generate specific shape

[Davide Masiello]

Shape of what? And how can it be specific if you use a random function?

I would suggest you take some time to edit your questoin and make it as clear as possible, providing the best code you could write.

Only then it will be possible to give you some help.

Still not sure what you mean, but I have edited my answer, please see if it sorts out your problem.
