Logical Arrays and for statements

My issue is the line commented. To make that line work CNccm needs to be a logical array the size of 2537*357. At the moment i am just getting a 2537*1 array, So over every loop it over writes the value. So basically at the end of the loop i expect to get a 357*1 matrix with values ranging between 0 and 1. Im really stuck if i individually put in values for i when calculating the CNccm value it works fine its just not working with the loop. can someone pleeeease help im getting desperate.

 rccm = zeros(357,357);
Crccm = zeros(357,2537);
CNccm = zeros(357,2537);
Nccm = zeros(2537,1);
Prob = zeros(357,1);

 for i=1:1:357
    for j=1:1:357;
    rccm(i,j) = sqrt((0.5*(jmag(i,1)-jmag(j,1)).^2)+((diffmag(i,1)-diffmag(j,1)).^2)+((diffmag2(i,1)-diffmag2(j,1)).^2));
hold on              
    end

 srt = sort(rccm);                      
r = transpose(srt(21,1:357)); 

    for k=1:1:2537;
Crccm(i,k) = sqrt((0.5*(jmag(i,1)-Cfjmag(k,1)).^2)+((diffmag(i,1)-Cfdiffmag(k,1)).^2)+((diffmag2(i,1)-Cfdiffmag2(k,1)).^2));
        end   
    rcontr = transpose(Crccm);     
    CNccm = (rcontr(:,i)) <= r(i,1);          %Need to make a [2537*357] Logical array
    Nccm(i) = sum(CNccm);                     
    Prob(i)= 1-((Nccm(i)/20)*(9/81)); 

    hold on
end

See if this works:

     CNccm(i,:) = transpose((rcontr(:,i)) <= r(i,1)); % Need to make a   
                                                      % [2537*357] Logical array
     Nccm(i) = sum(CNccm(i,:));

it has given me the answer in type double which is a massive help thanks.. but something is still not going right and i dont understand why.. i should get for Nccm a list of integer numbers ranging in size (Nccm counts up the number if 1's in CNccm) however i get zero for about 337 values then numbers from 338-357 I dont know why its doing this?? if i put a value of 1 in for i and do the calculation manually i get a non zero value.. the error is occuring somewhere in the two above lines..

actually i just realised that i dont want the variable as a double? just a logical array of 2537x357 ??
