How can I guarantee data is placed into the correct spot in a matrix?

I have data being placed into a 16x16 matrices from a loop and one piece is ending up in the wrong column despite the label. I have it designated as J(14,6) and despite all efforts I end up with the results in J(13,6).

That does not help. I started with (1,1) for the matrices and all the rest of the data was placed correctly.

MATLAB is ones based not zeros based. Does this change your question?

He (Doug) means tyhe indices in MATLAB start from 1 not 0. So you have J(1,1) as the first element and J(0,0) returns an error.

You need to use J(1:14,1:6) to access the first 14 rows and first 6 columns of J.
