Hi, I have a XY array matrix called A , the first column are the X values (column of the image) and the second Y values (rows of the image) and I need to create a BW image in which the points of the A matrix get color white in the image.
As an example, the A data could be:
And the image size should be , is that correct?
A = randi(20,[10 2]);
idx = sub2ind([20 20],A(:,2),A(:,1));
BW = false(20,20);
BW(idx) = true;
