The gradient is a vectorfield, i.e. a vector attached to every point of you space. The most clear way to draw it is to draw an arrow of length (4,2) starting from the point (2,1).

The vertical component of the vector (on the tangent plane) is equal to the magnitude of the gradient. This applet shows the surface defined by [math]f (x, y) [/math] along with the gradient vector [b] [math]gradf [/math] [/b] at the point [math]A= (x_0, y_0…

Nov 16, 2022 · In this section we introduce the concept of a vector field and give several examples of graphing them. We also revisit the gradient that we first saw a few chapters ago.

Dec 2, 2024 · Sketching Gradient Functions How can I sketch a function's gradient function? Using your knowledge of gradients and derivatives you can use the graph of a function to sketch the corresponding gradient function. The behaviour of a function tells you about the behaviour of its gradient function

Oct 11, 2015 · Here's a solution using sympy and numpy. This is the first time I use sympy, so others will/could probably come up with much better and more elegant solutions. now you can use numgradfun (1,3) to compute the gradient at (x,y)== (1,3).

Oct 18, 2018 · How do I plot a sampling of gradient vectors for fby using the vectorplot command? I’m confused how to use both these commands.

Sep 11, 2020 · You could use FancyArrowPatch to draw the gradients at a few selected positions. arrowstyle='simple', color='k', mutation_scale=10) Otherwise if you want to plot the whole vector field quiver might be an option: color='r', mutation_scale=10) . I added the line y = x in this plot and marked the point where this lines intersects with a contour line.

Apr 2, 2023 · Calling plt.quiver with reversed direction vector parameter (Gx and GY) should give you the expected results : plt.quiver(X, Y, -Gy, -Gx) Adding a bit of style and axis formating, here is how you'll get the expected figure
