moransI correlation of matrix gives output value greater than one

I am trying to calculate the moransI correlation of matrix, as W=true(3); mcor=moransI(matrix,W);

I am getting a matrix as output, I need one value, so I take the mean as mean(mcor(:));

Value is greater than one , while it must be in the range of -1 to 1, as a definition of correlation.

How to get the correct value, suggest me.

Perhaps you would be better to contact the author:

Since moransl.m is not a MathWorks' function or method.
