3D Surface Plot in MATLAB || z = sin(x)·cos(y) || Step-by-Step Tutorial for Beginners.
In this video, we’ll learn how to plot a 3D surface in MATLAB using the function:
z = sin(x) × cos(y)
This tutorial is perfect for beginners who want to understand how to:
✅ Define x and y ranges
✅ Use meshgrid to create a grid
✅ Calculate z values for the surface
✅ Plot the surface using surf
✅ Add axis labels and a title
✅ A colorbar to make the plot more informative (optional)
💡 MATLAB makes visualization simple and powerful. By the end of this video, you’ll be able to create and customize your own 3D plots with ease.

🚀 Code Used in This Video:
x = -3*pi : 0.1 : 3*pi;
y = -3*pi : 0.1 : 3*pi;
[x, y] = meshgrid(x, y);
z = sin(x) .* cos(y);
surf(x, y, z)
xlabel('x-axis')
ylabel('y-axis')
zlabel('z-axis')
title('Plot the surface z = sin(x).cos(y)')
