How to cut the signal from a specific point?

Hello everyone,

I have two signals with different length and I want to cut one of them to have two signals with the same length.

I have attached the figure that shows the two signals. I want to cut the section which is in the red circle.

Thank you in advance for your help

First, I create some random signals, to approximate the situation:

green_signal = 0.4*rand(1,265);
blue_signal = rand(1,210);
NG = numel(green_signal);

Now I make a plot similar to yours:

subplot(2,1,1)
plot(blue_signal,'b');
hold on
plot(green_signal,'g');
title('original')
xlim([1 NG]);

Now, perform the cutting of the "green" signal:

green_signal(numel(blue_signal)+1:end) = [];

Now another plot after cutting:

subplot(2,1,2)
plot(blue_signal,'b');
hold on
plot(green_signal,'g');
xlim([1 NG]);
title('after cutting green signal')
