Hii Friend,
I have set of coupled differential equations which i need to solve and plot using matlab.
I am confused on how to proceed.Do suggest me on how to proceed with it.
The final out needed is a plot of abs(B(1)) Versus delk versus Z as shown in the pic.

See the documentation on Ordinary Differential Equations.
First, follow the documentation and write your ODE function, then use the appropriate ODE solver (try ode45 first) to integrate it. If you have problems, describe them, completely copying and pasting any error messages that occur, and attach your script and your ODE function files. We will do our best to help you get your code running if you need our help.

No worries!
Thank you for following up.
I was curious as to how you incorporated the vector into your ODE function, as much to satisfy my curiosity as to help anyone else who searches for your Question with the same problem.

Hi strider I am usig bvp4c to solve coupled or non linear equation like velocity concentration temperature.. When i have to plot on velocity profile. I use the command plot (x1, y1(2, :)) for concentration 4 and temperature 6. If i have another linear equation like density of motile microorganism what number i should put.. To get the desired graph??
