matlab diff 2
If X is a vector, then diff(X) returns a vector, one element shorter than X , of differences between adjacent elements: [X(2)-X(1) X(3)-X(2) ... X(n)-X(n-1)]. If X is a ... ,This MATLAB function calculates differences between adjacent elements of X along the first array ... In practice, this means diff(X,2) is the same as diff(diff(X)) .

1-3 微分
1-3 微分. n 若要進行微分運算，可用diff 指令，例如：. syms a x f = sin(a*x^2); df = diff(f). 此時MATLAB 會自動決定f 的獨立變數是x，並對x 進行微分，得到的結果是. http://mirlab.org diff (MATLAB Functions)
