I want to rotate the properties fromi=201:600(x) and J=201:600.(Y) That is the properties inside the area inside this area should be rotated. Can someone please help me?

fid = fopen('moduli','r')
data = fread(fid, inf, 'single', 'ieee-be');
fclose(fid)
data = reshape(data,[800 800 3]);
for i=201,600
for j=201,600
end
end
figure(1)
pcolor(data(:,:,1))
axis tight;
shading interp;
colorbar;
set(gcf,'renderer','zbuffer')
print -dpng mod

Thank you so much for the reply. I meant to rotate the area mentioned. Some properties are assigned inside this area and the properties will automatically be re-assigned if it has been rotated. Hereby attaching the compressed version of moduli.

Hello,
To rotate to rotate the submatrix of data, the “imrotate” function can be used. In the example below, the rotation is limited to the region of interest with the surrounding areas being set as 0, and the extruding areas being cropped. However, this can be configured by the “imrotate” options as per the requirement.
data(201 : 600, 201 : 600, 1) = imrotate(data(201 : 600, 201 : 600, 1), 45, "bilinear", "crop");
The documentation on the “imrotate” function (https://www.mathworks.com/help/images/ref/imrotate.html) is helpful in this regard.
