Solving simultaneous differential equations symbolically on MATLAB

I need to solve the following differential equations (recommended method: Runge Kutta Gill integration)

(dc/dx) = (K*c-C_p)-c*(dP/dx)

(dP/dx)=(K*c-C_p)/c

K is a constant; C_p is just C with subscript p and is a constant; P and c are the variables.

Boundary conditions:
at x=0, C=C_w
at x=L, c=C_p

Please tell me how I could do this, since I've never done integration on MATLAB before!

It seems I need to solve the two equations and then integrate between the limits.
