Create a function that can do the following things:
Calculate the following integration :
g(k) = ∫f(x)*sin(k*x) dx, where f(x) is any mathematical function, and
the integration range is from -X to X
k=[0: 2*pi/X : 1/dx]
以上是題目
f(x)和上下線都由使用者輸入
然後下面是我打的程式碼
function onetwothree(f,X)
dx = 1e-6;
for k=0 : 2*pi/X : 1/dx
g = integral(f*sin(k),-X,X);
fprintf('g(%d)=%d\n',k,g);
end
然後去測試 onetwothree(@(x)x^2,1)
結果跑出來這樣
Undefined function 'mtimes' for input arguments of type 'function_handle'.
想請問大大我的程式碼問題出在哪

onetwothree(@(x,k) x.^2*sin(k),1)(function裡) g=integral(@(x)f(x,k),-X,X)答案不知道對不對 有值就是了
