How can I create a 3D mesh/surface chart with one matrix of data

Dear All, I am trying to convert the following simple code into a mesh or surface because at the moment I am only able to plot the single vectors of the matrix I have. I am pasting below a simple example where the first column is a column with dates and the other vectors contain the datapoints (my matrix is larger than this but the inciple stays the same)

T = [2001 3 5 7;

2002 4 6 7;

2003 8 10 11;

2004 7 13 7;

2005 4 15 12;

2006 2 16 10] %example of matrix where the first column contains the dates

a = T(:,1) %extract the 4 vectors that compose the matrix

b = T(:,2)

c = T(:,3)

d = T(:,4)

x = zeros(size(a))

x1 = ones(size(a))

x2 = x1 * 2

plot3(x, a, b); %plotting 3 vectors in a 3D chart where y-axis contains the dates, x-axis is a scalar %equalling to the number of to chart (i.e. 3 in this case, excluding the initial column with dates)

hold on;

plot3(x1,a,c);

hold on;

plot3(x2,a,d);

hold off;

% Example matrix
T = [2001 3 5 7; 
    2002 4 6 7; 
    2003 8 10 11;
    2004 7 13 7;
    2005 4 15 12;
    2006 2 16 10]; % Matrix where the first column contains the dates

% Extract the data
dates = T(:,1); % Dates
data = T(:,2:end); % Data points

% Create a grid for plotting
[X, Y] = meshgrid(1:size(data,2), dates);

% Plotting as a mesh
figure;
mesh(X, Y, data);
xlabel('Data Series');
ylabel('Year');
zlabel('Values');
title('Mesh Plot');

% Plotting as a surface
figure;
surf(X, Y, data);
xlabel('Data Series');
ylabel('Year');
zlabel('Values');
title('Surface Plot');
