Sir, how do i solve an ode with an array , using ode45? ODE is udY/dx=P, Y,P are arrays.

The ode45 initial conditions have to be a vector.
You have my interest, though. Why do you want them to be a matrix?

Respected Star Thank you very much!
I thought I took much time of your rest.
Well I have Pdot equation as one of the two more differential equations.
What I did is that as you said : I put initial condition of 6 variables (diagonal) of P initial matrix. And then inside program, I equated them in for loop with eye(y).
Any way your help and attitude to help is simply great.
In gratitude Abhijit
