MATLAB 미적.
미분 Examples: h = .001; x = 0:h:pi; diff(sin(x.^2))/h is an approximation to 2*cos(x.^2).*x diff((1:10).^2) is 3:2:19 If X = [3 7 5 0 9 2] then diff(X,1,1) is [-3 2 -3], diff(X,1,2) is [4 -2 9 -7], diff(X,2,2) is the 2nd order difference along the dimension 2, and diff(X,3,2) is the empty matrix. >> syms x>> diff(sin(x), x) ans = cos(x) 적분 int (S, v, a, b) S : 수식, v : 인자, a : 시작값, b : 끝값 Examples..
