You left out the important bit of the error, which is the one that told you on which line of your code the error occurred. I assume it's the Theme Copy [Gmag, Gdir] = gradient (Gx, Gy); line that gives you the error, since the 2nd argument to gradient must be a scalar value. Munshida P
WebThe gradient of a function f f, denoted as \nabla f ∇f, is the collection of all its partial derivatives into a vector. This is most easily understood with an example. Example 1: Two dimensions If f (x, y) = x^2 - xy f (x,y) = x2 −xy, which of the following represents \nabla f ∇f? Choose 1 answer:
WebCalculate Gradients using Signed Distance Map. Create a linearly interpolated map. map = signedDistanceMap (InterpolationMethod= "linear" ); Set the map data to an identity matrix to set the main diagonal of the map to occupied. Set top left quadrant as occupied. Calculate gradient in each corner cell of map.
