g = input ('Precision of zero to the left ');

h = input ('Precision of zero to the right ');

x = (e:f:d);

z = (g:h);

y = a*x + b;

plot(y,x,'b*');

hold on

for x = (e:f:d)

y = a*x + b;

if y==z

plot (y(x)==z,'b*')

disp (x)

end

Im trying to plot any points within the range g and h these numbers are supposed to be very close to zero any help would be greatly appreciated

Hi Aaron,

To emphasize points that meet your specified condition in a plot, you can utilize a different marker.

The following code snippet illustrates how to achieve this:

% rest of the code
% Identify and plot points where y falls within the specified range
for i = 1:length(x)
    if y(i) >= g && y(i) <= h  % Adjust the condition according to your requirements
        plot(x(i), y(i), 'ro', 'DisplayName', 'Points Near Zero');  % This will display the points with a red circle
        disp(['x = ', num2str(x(i)), ', y = ', num2str(y(i))]);
    end
end
