Monitor

Monitor[expr,mon]

generates a temporary monitor cell in which the continually updated current value of mon is displayed during the course of evaluation of expr.

Details

  • Monitor[Table[e,{x,…}],x] generates a monitor cell that shows the continually updated current value of x during the evaluation of the Table.
  • In a notebook, the monitor cell normally appears directly after the cell in which Monitor[expr,mon] is evaluated. The cell is deleted as soon as the evaluation of expr is complete.
  • If Print, PrintTemporary, or similar output is generated before the evaluation of Monitor begins, it will appear before the monitor cell.
  • Any expression, including graphics and controls, can be given for mon.
  • Monitor[expr,mon,delay] will delay the indicated number of seconds before generating the monitor cell. If the evaluation of expr is complete before then, no monitor is displayed.
