Library "columns" Error Tolerant Matrix Setter/Getter Operations. Easy ways to add/remove items into start and end of Columns as well as arrays to grow and shrink matrix.
if mismatched sizes occur the typified NA value will be there to prevent catastrophic crashing.
Rows and Columns are split into 2 libraries due to limitations on number of exports as well as ease of style (columns.shift(), rows.pop() )
pop(_matrix) do pop last Column off of matrix Parameters: _matrix: Matrix To Edit Returns: Array of Last Column, removing it from matrix
shift(_matrix) do shift the first Column off of matrix Parameters: _matrix: Matrix To Edit Returns: Array of First Column, removing it from matrix
get(_matrix, _clmnNum) retrieve specific Column of matrix Parameters: _matrix: Matrix To Edit _clmnNum: Column being Targeted Returns: Array of selected Column number, leaving in place
push(_matrix, _clmnNum, _item) add single item onto end of Column Parameters: _matrix: Matrix To Edit _clmnNum: Column being Targeted _item: Item to Push on Column Returns: shifted item from Column start
push(_matrix, _array) add single item onto end of matrix Parameters: _matrix: Matrix To Edit _array: Array to Push on Matrix Returns: Void
unshift(_matrix, _clmnNum, _item) slide single item into start of Column remove last Parameters: _matrix: Matrix To Edit _clmnNum: Column being Targeted _item: Item to Unshift on Column Returns: popped item from Column end
unshift(_matrix, _array) add single item into first Column of matrix Parameters: _matrix: Matrix To Edit _array: Array to unshift into Matrix Returns: Void
set(_matrix, _clmnNum, _array) replace an array to an existing Column Parameters: _matrix: Matrix To Edit _clmnNum: Column being Targeted _array: Array to place in Matrix Returns: Column that was replaced
insert(_matrix, _clmnNum, _array) insert an array to a new Column Parameters: _matrix: Matrix To Edit _clmnNum: Column being Targeted _array: Array to place in Matrix Returns: void
slideDown(_matrix, _array) add single item onto end of Column Parameters: _matrix: Matrix To Edit _array: Array to push to Matrix Returns: shifted first Column
slideUp(_matrix, _array) add single item onto end of Column Parameters: _matrix: Matrix To Edit _array: Array to unshift to Matrix Returns: poppeed last Column
pullOut(_matrix, _clmnNum) add single item onto end of Column Parameters: _matrix: Matrix To Edit _clmnNum: Column being Targeted Returns: removed selected Column
