Calculate a matrix based on value from another matrices

Hi. I want to calculate new value in matrix C and based on conditions from value of matrix P and R.

R=

[1    -0.136  0.036
-0.136    1            -0.327
0.036    -0.32          1]

P=

[1  1.02385610592401e-07  0.155888059376484
1.02385610592401e-07  1  5.36959056693074e-39
0.155888059376484  5.36959056693074e-39  1]

significant = zeros(size(P)) ;
significant(P<0.05) = 1 ;
positives=zeros(size(R));
positives(R>0) = 1 ;

I want to calculate C like this,

-1- In same row and column, I want to make value 1, if both matrices is one, and else will become zero.

Can you help me? Thanks

I already change the question, actually I forgot to edit when I've been out for a while.

Answer 1

n = size(P,2);
pp = P < .05;

C = sum(pp,2)/n;

[i1,j1] = find(pp.*(1:n));
E = cellfun(@(x)strjoin(x,','),accumarray(i1,j1,[],@(x){sort(D(x))}),'un',0);

At new edition of question

R = [1    -0.136  0.036
    -0.136    1            -0.327
     0.036    -0.32          1];

P = [1  1.02385610592401e-07  0.155888059376484
     1.02385610592401e-07  1  5.36959056693074e-39
     0.155888059376484  5.36959056693074e-39  1];

C = P < 0.05 & R > 0
