how to sum two dimensional variables? and store in a single dimensional variable?

R=3;

M=[2,4,8];

beta=8;

pa=9;

pb=7.2;

po=0:0.5:12;

for kk=1:length(M)

for ii=1:length(po)

    ko(ii)=floor(po(ii)*M(kk)/pa);

    psearch=union([0,pb],(M(kk)*po(ii)/(ko(ii)+1)));

    for i=1:1:length(psearch)

        pp=(M(kk)*po(ii)-psearch(i))/ko(ii);

        f(i)=(1-exp(-((2^R-1)/psearch(i))^(beta/2)))+ko(ii)*(1-exp(-((2^R-1)/pp)^(beta/2)));

end

    po_cap=min(f);

    if po(ii)>=pa

        for i=1:M(kk)

            p1i(ii,i)=po(ii);

        end

    end

    if po(ii)< pa

        for i=1:M(kk)-ko(ii)-1

            p2i(ii,i)=0;

        end

        for i=M(kk)-ko(ii)

            p3i(ii,i)=po_cap;

        end

        for i=M(kk)-ko(ii)+1:M(kk)

            p4i(ii,i)=(M(kk)*po(ii)-po_cap)/ko(ii);

        end

    end

end

end

I need to sum p1i,p2i,p3i,p4i and store in a variable s1power..how can be done?..can someone

suggest a solution?
