my case is like this

x=[1:0.1:100];

y=x^2;

in this case if I need only certain data x and y range from x= .5 to x=0.8 and plot those x and y how to do?

I need array data of x and y for the range using index

kindly help in this regard

There are several ways to create numbers in a specific range, one of them is following,

x = linspace(0.5, 0.8, 100); % specify the range and number of points
y=x.^2;
 
plot(x, y);
