can you tell me please, why you give a decision on that looping, just like "if y < nrow", " if ~= 1", and so on.If
I know that imgradient computes image local gradient. Is there a way to compute the global gradient? For example, for this image: Here is the global gradient: 카테고리 Image Processing and Computer VisionImage Processing ToolboxImage Segmentation and Analysis ...
Then I need to scope the computation of the function so thatdlfevalknows where to apply auto-diff. I do that by defining a function that evaluates the network and computes the gradient of interest. In this case: function [y, dy] = fun_and_deriv(x,theta) y ...
TensorFlow has a comparable facilitystop_gradient. These are useful when one needs copies ofexpressionsthat are treated as constants and whose gradient should not be calculated during learning. How does one implement such a thing in Matlab's Deep Learning Toolbox? (Possi...
Did you look in the help? Do you have the Image Processing Toolbox? Did you see imgradient() and imgradientxy()?
matlab dy_dx = diff(y) ./ diff(x); The resulting vectordy_dxcontains the approximated derivatives at each point. Another useful function for numeric differentiation in Matlab isgradient. Thegradientfunction computes the gradient, or the vector of partial derivatives, of a function at each point...

I have the data below in Matlab: However, when I plot it, yellow is given to the values close to 1 and dark blue to the values close to 0. How can I reverse the order of the colorbar, so that yellow is given to the values close to 0 and dark blue to the val...

Where do you use "radial splines" in the code you posted ? We must see the code (as plain ascii text, not as a graphics) with which you generated the splines. Then maybe we can tell how to get the gradient. It seems that "cscvn" would be the appropriate MATLAB function ...
