I have to make a matrix which contains elements in an ellipse shaped region, but I need to make ellipse region in such a way that larger axis of ellipse is inclined with angle θ with horizontal. With
Colorize the matrix should look like this:
I have employed two ways so far for this:
Graphics, followed by
MorphologicalComponentsand then use
Positionto get a list and then convert it into matrix.
Write the equation of an inclined ellipse as
f[x,y] = 0and then use condition
f[x,y] <= 0and run it on matrix coordinates to get the list and then finally convert it into matrix.
However, these two methods are a bit slow and I would like to use something like
DiskMatrix or any other way to make it faster.
