3D mesh plot

Hello, I wrote this code in order to get a 3D mesh plot based on those x,y,t values. is there any way to confirm that the plot would look like this? or i need to just trust Matlab with it? (added the plot)

%given data

x = [0 10 20 30 0 10 20 0 10 20 30];

y = [0 0 0 0 15 15 15 15 30 30 30 30];

t = [20 22 25 23 22 27 30 25 19 20 18 22];

%grid for x and y

%use unique so each value will be used once

[X,Y] = meshgrid(unique(x), unique(y));

%turning t into the same size as X and Y

T = reshape(t,length(unique(y)),length(unique(x)));

%3D plot for the values

figure;

mesh(X,Y,T);

xlabel('X');

ylabel('Y');

zlabel('T');

The ‘x’ vector is missing a ‘30’ value (supplied here).

I get a different result when I plot those data —

x = [0 10 20 30 0 10 20 30 0 10 20 30];
y = [0 0 0 0 15 15 15 15 30 30 30 30];
t = [20 22 25 23 22 27 30 25 19 20 18 22];

% Q = [size(x); size(y); size(t)]

xv = linspace(min(x), max(x), numel(x));
yv = linspace(min(y), max(y), numel(y));
[X,Y] = meshgrid(xv,yv);

F = scatteredInterpolant(x(:),y(:),t(:));               % Use 'scatteredInterpolant'
T = F(X,Y);

figure
surfc(X, Y, T)
colormap(turbo)
colorbar
xlabel('X')
ylabel('Y')
zlabel('T')

[Uy,yix] = unique(y);
Rows = mean(diff(yix));
X = reshape(x,Rows,[]);                                 % Using 'reshape'
Y = reshape(y,Rows,[]);
T = reshape(t,Rows,[]);

figure
surfc(X, Y, T)                                          % 'surfc'
colormap(turbo)
colorbar
xlabel('X')
ylabel('Y')
zlabel('T')

figure
meshc(X, Y, T)                                          % 'meshc'
colormap(turbo)
colorbar
xlabel('X')
ylabel('Y')
zlabel('T')

Experiment to get different results.
