Y) using matlab command.Revised for MATLAB 7.14 (Release 2012a). Y) and along the diagonal (i.e., w.r.t. Can anyone please help me in taking the analytical (partial) derivative of the function F along X (i.e., w.r.t. Here is a particular code. MATLAB: To take the partial derivative of a function using matlab.

Three typical volume-constrained stress minimization problems are presented to verify the effectiveness of sensitivity analysis code. The nonlinear optimization solver is chosen as the Method of moving asymptotes (MMA). The correctness of the analytical sensitivity is verified by comparison with finite difference approximation. The 3D sensitivity analysis for p-norm global stress measure is derived and explained in detail accompanied by corresponding MATLAB code. The 146 lines code includes the finite element analysis and p-norm stress sensitivity analysis based on the adjoint method. The ending value is not an integral distance from the start: A 1:6.3.This paper presents an efficient and compact MATLAB code for three-dimensional stress-based sensitivity analysis.
