how to make rotated utm grid in matlab

main.m
% Define the UTM zone and rotation angle
utmZone = 48; % For example, UTM zone 48 in India
rotationAngle = 45; % Rotation angle in degrees

% Define the grid spacing
gridSpacing = 1000; % Spacing between grid lines in meters

% Create a meshgrid of rotated coordinates
[x,y] = meshgrid(0:gridSpacing:10000, 0:gridSpacing:10000);

% Convert the rotated coordinates back to UTM
[lat, lon] = utm2ll(x, y, utmZone);

% Rotate the UTM grid
lon1 = lon*cosd(rotationAngle) - lat*sind(rotationAngle);
lat1 = lon*sind(rotationAngle) + lat*cosd(rotationAngle);

% Plot rotated UTM grid
figure;
plot(lon1, lat1, 'b.');
xlabel('Longitude');
ylabel('Latitude');
title('Rotated UTM Grid');
