**CIGAL Reference Manual, Chapter 3 (Functions): column**
===== Column -- Perform arithmetic column by column within a variable =====
**usage: varb2 = column(varb1,op)**

COLUMN combines all the values within a column of VARB1 into a single value
in VARB2, thus reducing a matrix variable to an array, or a solid to a matrix.
Column values are combined according to the operator, OP, which can be any of:
                      MAX, MIN, SUM, MEAN, or STDEV
Examples:
          mat1 = column(sol1,max)      ; convert solid to matrix of column maxima
          aray1 = column(mat1,mean)    ; find mean of each vertical column
