how to write a program to plot the signal {1, 2, 3, 4, 5} and also how to Represent this sequence x(n) = {0, 1, 2, 3, 4, 5}. in MATLAB.

please can someone offer a help to this.Thank you as you volunteer.

The question is not clear. How should the plot look like? What is "n"?

What ever come sin flower braces ({}) is a cell in MATLAB. A matrix comes in square braces ([]). You can check the class of the variable using class. It is better to have a matrix for calculations and plotting. YOu can plot your signal as below:

   mysignal = {1 2 3 4 5} ;   % it is a cell (check with _class(mysignal)_)
   mysignal = cell2mat(mysignal)   % convert to matrix using _Cell2mat_  
   plot(mysignal)     % plot using _plot_

Coming about the next question; regaridng sequence. If you have all same vectors, save them in a matrix. Like below:

X = zeros(5,5) ;
for i = 1:5
    X(i,:) = rand(1,5) ;
end

If your sequence is having different sized vectors, save them into cell. Like below.

X = cell(3,1) ;
X{1} = rand(!,5) ;
X{2} = rand(1,7) ;
X{3} = rand(5,1) ;

MATLAB is easy with rich documentation. REad about matrix indexing:
