Question

Create a matrix X so that the first row has values from 0 to 50 (default intervals), and the second row has values from 50 to 100. Let matrix Y equal to x10 and Z equal to x + y2 Create 4 subplots containing a mesh, surface, 3-Dimensional, and a surface-contour plot. Label with appropriate titles and labels. The plots should have a string look to them.

How do I solve using Matlab?

Answer 1

Please find the attached code..

clc;
clear all;
X = [0:1:50; 50:1:100];    % Here, 1 is interval (You can change it as per your needs)
Y = X.^10;
Z = X.*(Y.^2);
subplot(2,2,1);
mesh(X,Y,Z);
xlabel('X');
ylabel('Y');
zlabel('Z');
title('Mesh plot');
subplot(2,2,2);
surf(X,Y,Z);
xlabel('X');
ylabel('Y');
zlabel('Z');
title('Surface plot');
subplot(2,2,3);
plot3(X,Y,Z);
xlabel('X');
ylabel('Y');
zlabel('Z');
title('3-Dimentional plot');
subplot(2,2,4);
surfc(X,Y,Z);
xlabel('X');
ylabel('Y');
zlabel('Z');
title('Surface-Contour plot');
grid on;

The subplot command will create a figure grid for plots. Eg. subplot(i,j,k), it will create a figure grid with i rows and j columns (i*j number of figures), and 'k' is a figure number.

The output will look like..

Mesh plot Surface plot *1041 x 1041 10 10 N 5 N 5 10 10 100 100 1019 *1019 50 5 50 Y 0 0 X 3-Dimentional plot 5 Y 0 0 X Surface-Contour plot *1041 x1041 10 10 N 5 N 5 10 10 100 100 5 *1019 50 5 *2019 50 Y 0 0 х Y 0 0 х
