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];
y0 = 0;
[t,y] = ode45(@(t,y) 2*t, tspan, y0);
B: tspan = [0 5];
y0 = 1;
[t,y] = ode45(@(t,y) 2*t, tspan, y0);
C: tspan = [0 5];
y0 = 1;
[t,y] = ode45(@(t,y) 2*y, tspan, y0);
D: tspan = [0 5];
y0 = 1;
[t,y] = ode45(@(t,y) 2*t*y, tspan, y0);
A: tspan = [0 5];
y0 = 0;
[t,y] = ode45(@(t,y) 2*t, tspan, y0);
B: tspan = [0 5];
y0 = 1;
[t,y] = ode45(@(t,y) 2*t, tspan, y0);
C: tspan = [0 5];
y0 = 1;
[t,y] = ode45(@(t,y) 2*y, tspan, y0);
D: tspan = [0 5];
y0 = 1;
[t,y] = ode45(@(t,y) 2*t*y, tspan, y0);
举一反三
- 如何用Maltab求解 y'(t) = 2*t , y(0) = 0?
- (2006年)设f(χ，y)与φ(χ，y)均为可微函数，且φ′y(χ，y)≠0．已知(χ0，y0)是f(χ，y)在约束条件φ(χ，y)＝0下的一个极值点，下列选项正确的是 【 】 A: 若f′χ(χ0，y0)＝0，则f′y(χ0，y0)＝0． B: 若f′χ(χ0，y0)＝0，则f′y(χ0，y0)≠0． C: 若f′χ(χ0，y0)≠0，则f′y(χ0，y0)＝0． D: 若f′χ(χ0，y0)≠0，则f′y(χ0，y0)≠0．
