Ports

Output

Total Exec Time — Total execution time for the previous base rate tick

double

Presents the total execution time as of the previous sample time.

Task Exec Time — Task execution times for individual sample rates (optional)

vector of double

Presents the task execution times for individual sample rates in a multitasking model as of the previous sample time.

Dependency

When you select Measure task execution times, this port is visible.

Parameters

Measure task execution times — Show task execution times for individual tasks

‘off’ (default) | ‘on’

Makes visible the port Task Exec Time, which presents the task execution times for individual sample rates in a multitasking model as of the previous sample time.

Programmatic Use

Block Parameter: ShowTaskTimes

Version History

Introduced in R2017a

R2024b: Update to blocks with port names
