I have the following optimization problem that I want to solve in matlab:

    Objective: minimize summation of d(i) from 1 till N 
     where d(i) is either 0 or 1
  the constraints are:
      a(k,i)<= d(i) for every k and i 
     and summation of a(k,i) where i is from 0 till n is <=1 for all k 
     and summation of a(k,i) where i is from 0 till n and k from 1 till P is >=C(constant)
     a(k,i) is either 0 or 1

Is this solvable in cplex for  Matlab and what functions should I use?

This is an integer problem and can be solved with CPLEX through matlab, please read Getting started with CPLEX for MATLAB which should give you the basic to get started.
