I'm trying to code a black and white figure that is four quarter circles in a square grid. This is the image of what I want: https://docs.google.com/drawings/d/1FDyLv3zASGpJ3GCJ6r8ryEXfCbfaZN5fLGLTqLnKeSE/edit?usp=sharing. It will have a for statement and probably and if statement. The code below is not even close to what I want but illustrates the general setup.
m = 51; n = 51; maxX = m; maxY = n; A = zeros(maxX, maxY); for i = (1:maxX) A(i:51,i:51) = 1; if A(i:51,i:51) == 1; A(26,i:51) = 0; A(i:51,26) = 0; end end imagesc(A'); set(gca, 'YDir', 'normal'); colormap(1-gray); axis equal; axis tight;
