Find the gradient ofA(X)with respect toX. Thegradientfunction returns an unevaluated formula. gradA = gradient(A,X) gradA(X) =∇XA(X) Show that the divergence of the gradient ofA(X)is equal to the Laplacian ofA(X), that is∇X⋅∇XA(X)=ΔXA(X). ...
Our approach combining the semi-convexity of the squared distance function with a Riemannian property of the space seems to be of independent interest, and can be compared with Savar茅's work on the local angle condition under lower curvature bounds. Applications include the convergence of the ...
Calculate the gradient of the function f(x,y)=xy2+x2y for (x0,y0)=(2,3) ∇f= Gradient of a Function: Consider a two-variable function z=f(x,y) which represents some smooth surface. The gradient of this function gives a vector representing...
The gradient is an important tool that determines the rate and direction of the increase of a function or vector. It is a scalar-multivariable function that basically stores all the partial derivative information of another mutivariable function. The gradient of a function with var...
Find the gradient of the function f(x,y,z)=10x2y−6zcos(x) at the point (0,−5,3). Gradient: The gradient is an operator that can be operated on both vectors and scalar functions. The gradient operator can be operated on scalar functions by simple multip...
inverse of a function 对于一个one-to-one一对一的function(即如果x值不同,则对应的函数值f(x)就不同),如果我们将这个加工机器的功能反过来,则,可以得到另一个function,这个function就称为原来function的inverse function反函数。而已知函数的formula,y=f(x)求出反函数的方法三步我们需要谨记:互换x,y即得x=...
plotting a scatterplot in statistics and finding the line of best fit, which required calculating the error between the actual output and the predicted output (y-hat) using the mean squared error formula. The gradient descent algorithm behaves similarly, but it is based on a convex function. ...

It works as a standalone, single-cell formula. My reference to 365 was based solely on the use of the CONCAT function, which I (perhaps erroneously?) believed was only available to 365 subscribers. P.S. Why are you using CONCAT in the construction you posted? Seems superfluous to me. ...
