WebTo specify the learn rate, use the learn rate input arguments of the adamupdate , rmspropupdate, and sgdmupdate functions. To easily adjust the learn rate or use it for custom learn rate schedules, set the initial learn rate before the custom training loop. learnRate = 0.01; Web[FX,FY] = gradient(F) 返回矩阵 F 的二维数值梯度的 x 和 y 分量。附加输出 FY 对应于 ∂F/∂y，即 y（垂直）方向上的差分。每个方向上的点之间的间距假定为 1。 [FX,FY,FZ,...,FN] = gradient(F) 返回 F 的数值梯度的 N 个分量，其中 F 是一个 N 维数组。
