I have profile of earth. Surface plot and dimension is not same so How can I plot ?
clc;
close all;
clear all;
format long g;
load('dtm.mat'); %% using old data sets
% plotting the value %%
figure()
title('DTM of the surface of Mountain')
surf(transpose(hw),rw,Z);
xlabel('Longitude')
ylabel('Lateral')
zlabel('Vertical height')

Please check in dtm.mat attachment. Its hw=x=1*451 or rw=y=1*501 and z = 451*501. But my error is dimension should be same in surf. How can I deal with it?

You just need to transpose Z:
surf(hw, rw, Z')

There are a few errs and missing points in your code. Here is the corrected complete code.
clearvars;
format long g;
load('dtm.mat'); %% using old data sets
% plotting the value %%
[Hw, Rw] = meshgrid(hw, rw); % Meshgrid is required for 3D plots for x, y axes
figure()
title('DTM of the surface of Mountain')
surf(Hw,Rw,Z'); % Transpose of Z is necessary here
xlabel('Longitude')
ylabel('Lateral')
zlabel('Vertical height')
