matlaB中的simulink模块怎么实现模态分析的仿真啊
simulink怎么通过模块获得一组频响函数数据啊,高手指点迷津! 回复 1 # mft0226 的帖子Matlab自带的例子,用过,可行。
Fs = 1000; % Sampling frequency
T = 1/Fs; % Sample time
L = 1000; % Length of signal
t = (0:L-1)*T; % Time vector
% Sum of a 50 Hz sinusoid and a 120 Hz sinusoid
x = 0.7*sin(2*pi*50*t) + sin(2*pi*120*t);
y = x + 2*randn(size(t)); % Sinusoids plus noise
plot(Fs*t(1:50),y(1:50))

哦,看错问题了,sorry 没关系,仍然谢谢您!
