我正在尝试绘制一个包含定积分的函数。我的代码使用所有匿名函数。当我运行该文件时,它给了我一个错误。我的代码如下:
%%% List of Parameters %%%
gamma_sp = 1;
cap_gamma = 15;
gamma_ph = 0;
omega_0 = -750;
d_omega_0 = 400;
omega_inh = 100;
d_omega_inh = 1000;
%%% Formulae %%%
gamma_t = gamma_sp/2 + cap_gamma/2 + gamma_ph;
G = @(x) exp(-(x-omega_inh).^2./(2*d_omega_inh.^2))./(sqrt(2*pi)*d_omega_inh);
F = @(x) exp(-(x-omega_0).^2./(2*d_omega_0.^2))./(sqrt(2*pi)*d_omega_0);
A_integral = @(x,y) G(x)./(y - x + 1i*gamma_t);
Q_integral = @(x,y) F(x)./(y - x + 1i*gamma_t);
A = @(y) integral(@(x)A_integral(x,y),-1000,1000);
Q = @(y) integral(@(x)Q_integral(x,y),-3000,0);
P1 = @(y) -1./(1i.*(gamma_sp + cap_gamma)).*(1./(y + 2.*1i.*gamma_t)*(A(y)-conj(A(0)))-1./y.*(A(y)-A(0))+cap_gamma./gamma_sp.*Q(y).*(A(0)-conj(A(0))));
P2 = @(y) conj(P1(y));
P = @(y) P1(y) - P2(y);
sig = @(y) abs(P(y)).^2;
rng = -2000:0.05:1000;
plot(rng,sig(rng))
在我看来,当程序运行 plot 命令时,它应该将 rng 的每个值放入 sig(y) 中,并且该值将用作 A_integral 和 Q_integral 中的 y 值。但是,当我尝试运行该程序时,matlab 会引发错误。

关于我做错了什么的任何想法?
