columns

By kaigouthro
Updated
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
