scilab中求解常微分方程的问题

clf
clc

function dx=f(t,x)
    dx(1) = x(2)
    dx(2) = -B*(1-x^2)*x(2)-w*w*x(1)
endfunction

B = 5
w = 1
x0 = [10;100]
t = 0:0.01:10

x = ode(x0,0,t,f)
plot2d(t,x)

现在它在 scilab 控制台中显示以下问题...

 at line     3 of function f   ( /Users/mottelet/so.sce line 7 )
in builtin                ode 
at line    15 of executed file /Users/mottelet/so.sce

Submatrix incorrectly defined.
ode: An error occurred in 'lsoda' subroutine.

请告诉我我做错了什么并告诉解决方案。
