I have a 20x10 matrix of numbers, and I have found the column representation of the number I want, in this case it is 9, therefore, I know manually that the position in the matrix is column 1, row 9. Is there a way of Matlab telling me what matrix position it is in terms of row and column? I already know what number is in that position, but for the purposes of finding the original variables I would like to know it's position.

You actually mentioned it in the Tags: the find function.

That’s essentially it. You may get long vectors for ‘row’ and ‘col’, but the same rows in each will correspond to the indices of all elements that meet those criteria.
It’s always appropriate to include a tolerance as you did, to account for floating-point approximation error.
