How to plot repeated sequence in a file using stem3 command?

Hi,

I want to extract repeated channel response measurement from a file using loop and I want to plot using stem3 function. Can you please help with minimal working example. I shall be grateful.

Regards,

Mir

It is my understanding that you are trying to plot a “stem3” graph using data from a file that has multiple sequences of data. If this is the needed requirement, you may read the data into a variable, and then use it to plot a “stem3” graph. Additionally, you can then use the “hold on” command to plot each entry using a loop as per your use case on to the same plot.

Please feel free to refer to the documentation page linked below.

Here is a sample code for your reference.

x = randi(9, 2, 5);                        % Create Data 
y = randi(9, 2, 5);                        % Create Data 
z = randi(9, 2, 5);                        % Create Data 
axis([0  10    0  10    0  10])            % The ‘axis’ Call Must Be Placed Here 
figure(1) 
hold on 
for i=1:2 
    stem3(x(i,:), y(i,:), z(i,:)) 
end 
hold off

Thanks! I have know about this. I wanted to know how to extract repeated sequence from row vector which I cant plot using surfc. However, I have produced plot of the data using surf and surfc but it's not smart.
