WebJan 12, 2024 · Depending on your toolbox version, there are several ways of doing this. In R2016a and later, the evaluateGradient function enables you to evaluate (interpolate) the gradient at arbitrary points, including along the boundary. In earlier toolbox versions, you can use the pdegrad function to give the gradient in each mesh triangle (the gradient … The gradient (or gradient vector field) of a scalar function f(x1, x2, x3, …, xn) is denoted ∇f or ∇→f where ∇ (nabla) denotes the vector differential operator, del. The notation grad f is also commonly used to represent the gradient. The gradient of f is defined as the unique vector field whose dot product with any … See more In vector calculus, the gradient of a scalar-valued differentiable function $${\displaystyle f}$$ of several variables is the vector field (or vector-valued function) $${\displaystyle \nabla f}$$ whose value at a point See more Relationship with total derivative The gradient is closely related to the total derivative (total differential) $${\displaystyle df}$$: … See more Level sets A level surface, or isosurface, is the set of all points where some function has a given value.
