When looking at short term memory, a portion of it is the active working memory.

One way to look at the active working memory is like matrix multiplication.

Let’s say one gets a 5 digit number. It is fairly simple to return that number in the same order as given, which would equate to the identity matrix.

If one had to invert the order of number, then the diagonal of the matrix would be flipped compared to the identity matrix, so equating to a negative determinant.

Now imagine if one had to do more complex calculations like ordering the months of the year alphabetically. Creating a matrix that transposes the months vector is initially not that simple, though once instantiated, it becomes quite simple to repeat.

Depending on how many row alterations are needed, starting from the identity matrix could be a way to quantify the complexity of the task.
