MATLAB: How to plot the first 200 points of each vector on the same graph

graphhandelMATLABplotvector

what would I have to put in the plot command in order to plot only the first 200 points of each vector vs. t on the same graph?

load handel

sound (y,Fs)

multiplier = 0.10;

noise = randn(length(y),1) * multiplier;

sound_w_noise = y + noise;

sound (sound_w_noise, Fs)

t = 1:length(y);

plot(???)

plot(t(1:200),y(1:200))

You are defining t to run from 0 to 5 in increments of 1/44100, so it will contain 220501 elements (including 0)

Do this:

t = 0:1/44100:5-(1/44100);
plot(t,record)

Note that your code does not follow the guidelines given to you: the tic and toc are supposed to be before and after the sum statement, but you have put them around the randi statement.

You might end up with something like this:

R = 200;
C = 200;
X = randi([-100,100], R, C);
% sum in one statement
tic
Y = sum(X(:));
toc
% sum in a loop
Z = 0;
tic
for rr = 1:R
    for cc = 1:C
        Z = Z + X(rr,cc);
    end
end
toc
