Equating and plotting the ratio of two sets of data having unequal length.

Hello, I'm a beginner in matlab. I'm having problem in plotting a graph on matlab. I want to plot curve2：curve1. curve1 and curve2 has unequal length nad also the x axis is unequal. kindly help me.

curve1 curve2

x y x y

100 50 100.1 30

200 70 100.4 20

200.5 60 100.5 40

300 20 200 50

400 90

Read the doc for plot function. https://in.mathworks.com/help/matlab/ref/plot.html

In the simplest form, create variables for the two curves:

data1 = [100 200 200.5 300 400;50 70 60 20 90];
data2 = [100.1 100.4 100.5 200;30 20 40 50];
% Plot the first data set with a blue line
plot(data1(1,:),data1(2,:),'b')
% Tell Matlab to keep plotting curves on the same Figure 
hold on
% Plot the second data set using a red curve
plot(data2(1,:),data2(2,:),'r')

If you examine the help for plot you will find out how to set other parameters for the graph.
