Question

I would like to know how to plot two graphs in matlab and find where they intercept.

Answer 1

For this just I'll write code by taking example so that you can understand

% define x Axis and evaluate functions

x_points = -5:0.1:5;

function1 = -x+1;

function2 = x+1;

index_intersection = find(function1 == function2);

x_value_intersection = x_points(index_intersection);

y_value_intersection = function1(index_intersection);

% plot functions and intersection point:

curve1 = plot(x_points, function1);

hold on

curve2 = plot(x_points, function2);

intersection = plot(x_value_intersection, y_value_intersection,...

'Marker', '+', 'MarkerSize', 6, 'Color', 'r');

For your reference i i attached the code and graph which i have did my desktop

just try this example you can understand

If you have any questions please let me know

Please give me thumb up
