[gnuastro-commits] master a84aa87: Corrections in multi-operand Arithmetic operators

branch: master
commit a84aa8794e953a4e39329613be643c36094fe4a6

    Corrections in multi-operand Arithmetic operators
    
    In the median operator, the `++a[i]' (from the wrong implementation that
    was corrected in the last commit) still remained. It is now removed with
    this commit. Also a comment was corrected in calculating the mean and std
    operators.
