BUILT-IN MATHEMATICA SYMBOL
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.
- 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.
