Created page with "=Array Filter Functions (SomeTakeDropOrAllFlag, SomeFunction, SomeParameter)= ==Array.filteroncondition(SomeTakeDropOrAllFlag, SomeFunction, SomeParameter)== Apply a function..."

New page

=Array Filter Functions (SomeTakeDropOrAllFlag, SomeFunction, SomeParameter)=

==Array.filteroncondition(SomeTakeDropOrAllFlag, SomeFunction, SomeParameter)==
Apply a function to an array with parameters, and return list that matched/not matched/all

==Array.filteroncolumn(SomeCondition, SomeExtractColumns, SomeFilterOnColumn)==
SomeExtractColumns are the columns that are extracted, and filters are applied on SomeFilterOnColumn or column 0
1..100.filteroncolumn(">5")

==Array.filteronrow(SomeCondition, SomeExtractRows, SomeFilterOnRow)==
SomeExtractRows are the rows that are extracted, and filters are applied on SomeFilterOnRow or row 0
[1..100].filteronrow("<5")

gives

		+
		+	Please note that "asvector" implies each row in the array is treated as one to check the condition (like a vector).
		+
		+	For example, [1..10,2..3].collectwhileasvector("x[0]<5") will give the answer as the input itself, because in both rows, x[0] <5 is true. Here for each vector (or row), the function is applied to check if it should be collected or not.

	Generally the flag means:		Generally the flag means:
