MATLAB：如何将参数传递给函数？
 

我有以下功能：

function ypdiff = ypdiff(t,y) a = 0.01; b = 0.1; ypdiff(1) = -a*y(1)*y(2); ypdiff(2) = b*y(1)*y(2)-b*y(2); ypdiff(3) = b*y(2); ypdiff = [ypdiff(1) ypdiff(2) ypdiff(3)]'; 如果要解决此问题，可以按以下方式调用ode45函数：

[ty] = ode45(@ypdiff, [to tf], yo); 但是，如果要将参数传递给此函数，我将如何使用ode45函数？具体来说，我正在尝试以下公式：

function ypdiff = ypdiff(t,y,u) a = 0.01; b = 0.1; ypdiff(1) = -a*u*y(1)*y(2); ypdiff(2) = b*u*y(1)*y(2)-b*y(2); ypdiff(3) = b*u*y(2); ypdiff = [ypdiff(1) ypdiff(2) ypdiff(3)]';

您可以在matlab中使用[URL="http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_prog/f4-70115.html"]匿名函数[/URL] （类似于其他语言中的lambda函数）：

u = 1.2; [ty] = ode45(@(t, y) ypdiff(t, y, u), [to tf], yo);
