Hello ! can anybody tell me where am wrong.i have 179789 by 3 dimensions matrix. when am trying to get sum of all three axis to get one column vector the result is 1 by 179789 , but the desired result is 179789 by 1. looking for kind response

if true
  % code
i=1
for i=1:m 
  acc(i)=sqrt((x(i)^2+y(i)^2+z(i)^2));
end
end

Answer 1

[Andrei Bobrov]

acc = zeros(m,1);
for ii = 1:m 
    acc(ii)=sqrt((x(ii)^2+y(ii)^2+z(ii)^2));
end

or

Let A - your array (179789 x 3)

acc = sqrt(sum(A.^2,2));
