面试题与答案

'ode45' is a function used for solving ordinary differential equations (ODEs) numerically.

Example:

function dydt = myODE(t, y)
  dydt = -y + t;
end
[t, y] = ode45(@myODE, [0, 5], 1);

'fft' is used for computing the discrete Fourier transform (DFT) of a sequence or signal.

Example:

x = [1, 2, 3, 4];
X = fft(x);

Handle graphics refers to the system in MATLAB where graphical objects (plots, figures, axes) are represented by handles, allowing easy manipulation and customization.

Example:

figure;
plot([1, 2, 3], [4, 5, 6]);
h = gcf;
