Use memcpy for vector assignment
Description
Optimize code generated for vector assignment by replacing for
loops with memcpy.
Category: Optimization
Settings
Default: On
On
Enables use of
memcpyfor vector assignment based on the associated threshold parameter Memcpy threshold (bytes).memcpyis used in the generated code if the number of array elements times the number of bytes per element is greater than or equal to the specified value for Memcpy threshold (bytes). One byte equals the width of a character in this context.
OffDisables use of
memcpyfor vector assignment.
Dependencies
This parameter requires a Simulink® Coder™ license.
When selected, this parameter enables the associated parameter Memcpy threshold (bytes).
