rows

By kaigouthro
Updated
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
