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