求高人指点matlab如何制表,如求由t=0:pi/12:pi;x=cos(t);x1=sin(t)构成的3列14行的表
急求matlab问题,>> t=0:0.2:3*pi;x=exp(-t).*sin(t);plot(t,x) 前面的 t
用MATLAB绘出f(t)=u(cos t)在(-3*pi,3*pi)之间的波形求代码
Matlab u(x,t)=sin(5*pi*x)cos(5*pi*t)+2sin(7*pi*x)cos(7*pi*t)
x=4*sin(2*pi*0.01*t).*sin(2*pi*3*t)+2*cos(pi*t*t/4);在matlab中
matlaB函数问题t = -pi:0.01:pi;x=cos(t)-sin(3*t);y=sin(t)+cos(t);
y=cos(10*t*pi)+cos(40*t*pi);t属于[0,1],求这个函数的EMD分解matlab程序,画出图
matlab中t=linspace(0,2*pi,100);x=[t;t]';y=[sin(t);cos(t)]';pl
我的matlab程序哪里错了? t=0:0.01:2*pi x=cos(t)^3 y=sin(t)^3 plot(x,y
MATLAB求助,用FFT直接计算x=cos(2*pi*40*t)+2sin(2*pi*120*t)+w(t)的功率谱.
t=0:pi/100:10*pi; x=2*(cos(t)+t*sin(t)); y=2*(sin(t)-t*cos(t
matlab问题,>> t=0:0.2:3*pi;x=exp(-t).*sin(t);plot(t,x) >> t=0:
matlab如何画出f=sinc(40*t)*cos(140*2*pi*t)的频谱图
