/** | |||
* Check if the given formula should be evaluated in array mode. | |||
* | |||
* <p> | |||
* Normally, array formulas are recognized from their definition: | |||
* pressing Ctrl+Shift+Enter in Excel marks the input as an array entered formula. | |||
*</p> | |||
* <p> | |||
* However, in some cases Excel evaluates tokens in array mode depending on the context. | |||
* The <code>INDEX( area, row_num, [column_num])</code> function is an example: | |||
* | |||
* If the array argument includes more than one row and row_num is omitted or set to 0, | |||
* the Excel INDEX function returns an array of the entire column. Similarly, if array | |||
* includes more than one column and the column_num argument is omitted or set to 0, | |||
* the INDEX formula returns the entire row | |||
* </p> | |||
* | |||
* @param ptgs parsed formula to analyze | |||
