Hello all,

I am a newbie to Matlab.

I want to solve the first order differential equation.

I have 6 equations.

p10'(t)=p10(t)(-M1+M1(t10+t11)+M1*t11)+P20(t)(M1*t10)+P01(t)(M2*t2 1)+p21(t)(M2*t20)

p20'(t)= .....

.....

.....

....

.....

my teacher told me that at the end of solving , p10+p20+p....+...+..+..=1 and i have to plot that i get "1".

could anyone help me how to write ?

Thanks a lot.
