I'm not sure what tw1r1 is supposed to be. I'm going to substitute something there.
mytestnumber=37;
mtr11w1s=zeros(3,3);
for rr1=1:numel(strr1)
%mtr1=SDR2MT(strr1( rr1),dpr1( rr1),rkr1( rr1)) %%%% Result: 280 3*3 matrixm
mtr1=ones(3); % i don't have SDR2MT, so this is just a dummy
mtr1n=mtr1/mytestnumber;
for z=1:numel(mtr1n)
%mtr11w1s=mtr11w1s+mtr1n(z); % you sure you don't mean to be doing
mtr11w1s(z)=mtr11w1s(z)+mtr1n(z); % something like this?
end
end
mtr11w1s
I'm still not really sure if this is doing what you intend it to do. Do you have a written expression for the summation you're trying to do?
Also, as a tip:
a=rand(3,3); [length(a) numel(a)]
shows that if you want to step through all the linear indices of a 2D array, you shouldn't be using length()
ans =
3 9
