我创建了一个零向量，名为
result = zeros(1,20); 在GNU Octave GUI上，我想用for循环的积分估计值填充零。
a = 0; b = 3; f = @(x) sin(10 *x.^2); for i = 20 n = 2.^i; dx = (b - a) / n; left = a:dx: (b - dx); right = (a+dx) :dx:b; h1 = f(left); h2 = f(right); areas = (h1 + h2) ./ 2 .* dx; totalarea = sum(areas) endfor 谁能告诉我如何用上面的for循环中的totalarea值填充result矩阵？
