size() function returns wrong size

i have the following line of code:

s = size(k_distances)

k_distances is a 1x1 matrix:

but the size function returns a size of 1x2:

and then:

 k_labels = zeros(s);

returns a 3x1 matrix that not all zeros!!

any idea what is happening?

thank you

May be k_distances variable is called inside another loop and its size is varying. Can you show full code ?

Please don't post pictures of your code. You can paste in text more easily, and that text can now be copied by those who would try to help you.

John, I posted both code and pictures. thank you :)

Vasishta, turns out my break point was further along the script and I manged to change k_labels much after the assignment. my bad.

k_labels should return 1x1 array with value of zero.

Did you clear workspace from previous runs?

From the documentation on function size

sz = size(A) returns a row vector whose elements are the lengths of the corresponding dimensions of A. For example, if A is a 3-by-4 matrix, then size(A) returns the vector [3 4].

If A is a table or timetable, then size(A) returns a two-element row vector consisting of the number of rows and the number of table variables.
