Matlab Code 如下1 2 3 4 5 6 7 for i = 1 : n thetaPlus = theta; thetaPlus(i) = thetaPlus(i) + EPS; thetaMinus = theta; thetaMinus(i) = thetaMinus(i) - EPS; gradApprox(i) = (J(thetaPlus) - J(thetaMinus)) / (2 * EPS); end最后检查 gradApprox 是否约等于之前计算的...
If you notice discrepancies between the network in MATLAB and in Simulink, please check that the initial values are set properly in the Simulnk block using 'getsiminit'. Refer to the attached script for a simple example on how to do so. ...
