But, my image contains an elliptical object and I would like to get all the pixels within the ellipse. Thresholding did not wo... 17 May 2010 11:18

problem with reducing of precision
Hi , I have two variable (x1 and y1), which y1 is a result of interpolation "interp1". I want to calculate theta as below, but because of interp1, "ans" for each theta is not 0 (x=x1, y=y1, then theta(i) suppose to be 0 ). Then i tried to reduce the precision of y1 with fixpt_interp1, but it doesn't work. How can I ... 17 May 2010 10:12
