How can I plot this surf

on a cylindrical surface, like this?

% Step 1: Create the heatmap data
% Example heatmap data
heatmapData = peaks(50);  % Replace this with your actual heatmap data
[nRows, nCols] = size(heatmapData);

% Step 2: Generate the cylinder coordinates
theta = linspace(0, 2*pi, nCols);
z = linspace(0, 1, nRows);
[Theta, Z] = meshgrid(theta, z);
X = cos(Theta);
Y = sin(Theta);

% Step 3: Map the heatmap data onto the cylindrical surface
figure;
surf(X, Y, Z, heatmapData, 'EdgeColor', 'none');
colormap(jet);  % Adjust colormap as needed
colorbar;
title('Heatmap Mapped onto a Cylinder');
xlabel('X');
ylabel('Y');
zlabel('Z');

% Adjust the view for better visualization
view(3);
axis equal;
