Afternoon-
  I am trying to subtract a matrix, basically a vector of 28 values, each by
the same number to account for differences in regression fitting. I am
taking the 1x28 and minus it by the mean value of the matrix, each number.
The result I receive is a 1X29 matrix. Does anyone know why the result has
an extra value?
