Kindly requesting your assistance, I am running the following code and I am getting some errors. I am trying to get the partial derivative of a matrix in terms of X and Y. Based on the research I have conducted, it says that I could utilize the gradient option, but the error says "too many output arguments".
Also, for integrations would it be possible to get the feedback if I am coding it correctly. The X integration is from 0 to 4 and y from 0 to 3. I ran the code, but since I am getting the error for the partial derivative the code will not run the last part.
D=(E/(1-v^2))*[1 v 0;v 1 0; 0 0 ((1-v)/2)];
