以下哪一项属于二阶齐次线性差分方程?
A: y(t+2)-3*y(t+1)+y(t)=0
B: y(t+2)-3*y(t+1)+y(t)=2
C: (y(t+2))^2-3*y(t+1)+y(t)=0
D: y(t+1)+3*y(t)=0
A: y(t+2)-3*y(t+1)+y(t)=0
B: y(t+2)-3*y(t+1)+y(t)=2
C: (y(t+2))^2-3*y(t+1)+y(t)=0
D: y(t+1)+3*y(t)=0
举一反三
- 已知f1(t)=u(t+1),f2(t)=u(t+2)-u(t-2),设y(t)= f1(t)* f2(t),则y(0)等于() A: 0 B: 1 C: 2 D: 3
- 下列Matlab代码,能求解微分方程 y'(t) = 2*t , y(0) = 1的是( ) A: tspan = [0 5];<br> y0 = 0;<br> [t,y] = ode45(@(t,y) 2*t, tspan, y0); B: tspan = [0 5];<br>y0 = 1;<br>[t,y] = ode45(@(t,y) 2*t, tspan, y0); C: tspan = [0 5];<br>y0 = 1;<br>[t,y] = ode45(@(t,y) 2*y, tspan, y0); D: tspan = [0 5];<br>y0 = 1;<br>[t,y] = ode45(@(t,y) 2*t*y, tspan, y0);
- 一振幅为A、周期为T、波长为λ平面简谐波沿X负向传播,在X=(1/2)λ处,t=T/4时振动相位为π,则此平面简谐波的波动方程为:() A: y=Acos(2πt/T-2πx/λ-1/2π) B: y=Acos(2πt/T+2πx/λ+1/2π) C: y=Acos(2πt/T+2πx/λ-1/2π) D: y=Acos(2πt/T-2πx/λ+1/2π)
- 给定两个连续时间信号x(t)和h(t),若x(t)*h(t)=y(t),则x(t+1)*h(t-2)= A: y(t) B: y(t-1) C: y(t-2) D: y(t+1)
- 已知X=1,Y=2,T=0 经程序段X=T:T=Y:Y=T 赋值后 X,Y 值分别为()
