ARRAY FUNCTIONS

A listing of the Array functions are given below:

Function name Parameter

Function Name Parameters Notes
$ Apply functions to each element of array
$$ Apply functions to each row of array
$$$ Apply functions to each column of array
$$F Function/Array of Functions Append results of functions to each row
$A Parameter Get attributes from an array of objects
$C Function/Array of Functions, Optional Parameters, Column index to apply Apply a function with parameters to a column
$CELLS Function/Array of Functions, Optional Parameters, Row/Column Area indices to apply Apply a function with parameters to a cell area
$d Get the diagonal of an array
$diag Same as get the diagonal of an array
$dth Get the dth diagonal of an array
$R Function/Array of Functions, Optional Parameters, Row index to apply Apply a function with parameters to a row
$X Combines two arrays using an across operation. Reverse is .X$
$x Same as $X
$_ Apply a function to the entire array as one aggregate call
__$ Mode, Functions, Parameters Using a mode (value, valuebyrow, index etc), apply a function to the cells with parameters
ac ColCount Add columns
accumulate Total Accumulate each element with the next and give a cumulative result. Start from Total if need be.
accumulatewith CumulateFunction, CurrentResult Accumulate each element with the next using the function and give a cumulative result. Start from Total if need be.

X$ Combines two arrays using an across operation in reverse. Opposite of .$X
x$ FunctionArray, OffsetArray, ScaleArray, GiveIndicesAlso,DoCentering Apply a function array to the array, with offsets and scales applied, with indices or centering as requested
xy Apply a function array to the array, with offsets and scales applied, with indices
xypanel FunctionArray, OffsetArray, ScaleArray, GiveIndicesAlso Apply a function array to the array, with offsets and scales applied, with indices, centered by default at 0. Useful to create contour panels with inputs to apply functions on.
