Matlab 绘图图

Question

我正在尝试绘制以 phi 移动的方波的傅里叶级数，但出现此错误：

parse error near line 9 of file /home/cihad/Masaüstü/grafik.m syntax error

但是第 9 行没有任何问题

t = 0:0.001:2*pi;
A = 12;
n = 3;
p =pi/6;
fourier = 0
for n=1:2:100
    
    fourier_an = A*(2*sin(n*p)*cos(n*pi)-2*sin(n*p)))*cos(n*t)/(n*pi); ---> line 9
    fourier_bn = A*(2*cos(n*p)-2*cos(n*pi)*cos(n*p)+cos(n*p))*sin(n*t)/(n*pi);
    fourier = fourier_an + fourier_bn + fourier;
  
end

plot(t,fourier);

Answer 1

有一个不应该出现的括号。尝试：

t = 0:0.001:2*pi;
A = 12;
n = 3;
p =pi/6;
fourier = 0;
for n=1:2:100
    
    fourier_an = A*(2*sin(n*p)*cos(n*pi)-2*sin(n*p))*cos(n*t)/(n*pi);
    fourier_bn = A*(2*cos(n*p)-2*cos(n*pi)*cos(n*p)+cos(n*p))*sin(n*t)/(n*pi);
    fourier = fourier_an + fourier_bn + fourier;
  
end

plot(t,fourier);
