how to insert rand noise for this?

filename = 'hafis.CSV';

M = csvread(filename);

N=100;

x=M(:,3);

Y=M(:,4);

N=100;

subplot(2,2,1)

plot (x,Y,'linewidth',2)

title('Arc Signal')

xlabel('TIME')

ylabel('VOLTAGE');

You can use rand() to produce a vector (or matrix/array) of random values between 0:1. I subtracted 0.5 from those random numbers to center them around 0. Then I scaled them by a factor of 2 to demonstrate how to scale the random noise. Then simply add the noise to your data.

xrand = (rand(size(x))-0.5) * 2; 
yrand = (rand(size(Y))-0.5) * 2; 

plot (x + xrand, Y + yrand, 'linewidth', 2)

By the way, you defined N twice in your code.
