Hi Neeraj!
I understand that you're not able to see the plots. This is because the default marker symbol for plotting a line in MATLAB is no marker symbol. This means that by default, MATLAB will plot only a line connecting the specified data points, without any markers at the points themselves. Here, since you're plotting points individually, so no lines are displayed either.
You can modify your code to change the marker symbol to square like this:
for k = 0:0.1:2
for j = 0:10:90
x = k^2./j;
plot(k,x,'s')
hold on
end
end
For more information on plot, markers and its styling, please refer to the following documentation: https://www.mathworks.com/help/matlab/ref/plot.html
