在Matlab里,我的t=0:0.005:1; sig=80*sin(10*pi*t)*sin(60*pi*t);运行不
在Matlab里,我的t=0:0.005:1; sig=80*sin(10*pi*t)*sin(60*pi*t);运行不
在matlab中sin(t).和sin(t)有什么区别 例如:t=0:pi/20:2*pi y1=sin(t).*sin
x=4*sin(2*pi*0.01*t).*sin(2*pi*3*t)+2*cos(pi*t*t/4);在matlab中
matlab中问题:x = A1 * sin(2 * pi * f1 * t) + A2 * sin(2 * pi *
matlab绘图中的语法t=0:0.1:2*pi;y=sin(t);plot(t,
sin(pi*t)/(pi*t)怎么用matlab实现
Matlab u(x,t)=sin(5*pi*x)cos(5*pi*t)+2sin(7*pi*x)cos(7*pi*t)
t=0:pi/100:10*pi; x=2*(cos(t)+t*sin(t)); y=2*(sin(t)-t*cos(t
matlab中假设t=0:0.1:2*pi;为什么y=t.*sin(t).*sin(t)不等于y=t.*(sin(t))
matlab问题,>> t=0:0.2:3*pi;x=exp(-t).*sin(t);plot(t,x) >> t=0:
matlab中t=linspace(0,2*pi,100);x=[t;t]';y=[sin(t);cos(t)]';pl
高中数学f(t)=1+Cos(2000*Pi*t)+Sin(4000*Pi*t)
