class_docstr: Provides methods to allow conversion between sheet and matrix
  coordinates.
docstr: Convert a floating-point location (float_row,float_col) in
  matrix coordinates to its corresponding location (x,y) in
  sheet coordinates.
  
  Valid for scalar or array float_row and float_col.
  
  Inverse of sheet2matrix().
