                 URL: http://tools.oasis-open.org/issues/browse/OFFICE-2651
             Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
          Issue Type: Sub-task
          Components: OpenFormula
    Affects Versions: ODF 1.2 Part 2 CD 2

"Array Functions"
This categorisation seems to me to be inconsistent. Functions which 
return arrays are:
MINVERSE, MMULT, MUNIT, TRANSPOSE, FREQUENCY, GROWTH, LINEST, LOGEST, 
TREND
Functions which have ForceArray parameters are:
MDETERM, MINVERSE, MMULT, SUMPRODUCT, SUMX2MY2, SUMX2PY2, SUMXMY2, 
CORREL, COVAR, FORECAST, FTEST, INTERCEPT, MODE, PEARSON, PROB, RSQ, 
SLOPE, STEYX, TTEST (and LOOKUP sometimes).
This doesn't relate to the current functions listed as array functions. 
We have for instance SUMPRODUCT listed as an array function (but it's 
really a maths function) but MODE listed in stats (OK) - but both force 
array_mode calculation. Surely either both should be 'array functions' 
or both where they belong.
Perhaps only matrix functions should be in this category: MINVERSE, 
MMULT, MUNIT, TRANSPOSE, MDETERM. It could then be called 'matrix 
functions'.
