In an assignment A(I) = B, the number of elements in B and I must be the same, error.

x =

   4

   5

   6

   7

   8    %5x1

X =

   1

   2

   3

   4

   5

   6    %6x1

q=6;

for i=1:q

   dk(i)=x-X(i)

end

%it gives me the error.

%in this statement, I wanna create this situation,

dk(1)=x-X(1)

dk(2)=x-X(2)

dk(3)=x-X(3)

dk(4)=x-X(4)

dk(5)=x-X(5)

dk(6)=x-X(6)

What kind of loop I need to create these "dk".

Answer 1

[Andrei Bobrov]

x - vector -> dk1 = x-X(1), here dk1 - vector with length of x

in your case dk - matrix with size 6 x 5:

dk = zeros(numel(X),numel(x));
for jj = 1:numel(X)
    dk(jj,:) = x - X(jj);
end

or

dk = bsxfun(@minus,x(:)',X(:));
