Hi, how would I modify the following code if I only want to extract the odd rows in the output matrix. The output is generated by ODE45 and I am referring to the third variable. I have already tried to use the matrix indexing in matlab but it's not working. How would I go about this? If my output is given as below?
m = y(:,3);

请先登录，再回答此问题。

m=y(1:2:end,3);
