se_setseeds - Set seed values for blocks with random number generators

Syntax

Description

se_setseeds(seedstruct) sets the seed parameter values for all SimEvents blocks specified in seedstruct.

se_setseeds(seedstruct,sysid) applies the seed values to the system sysid, overriding the system specified in the system field of seedstruct.

oldseedstruct = se_setseeds(seedstruct) or oldseedstruct = se_setseeds(seedstruct,sysid)stores the original seed values in oldseedstruct before setting them to the values specified in seedstruct.

[oldseedstruct, status] = se_setseeds(seedstruct) or [oldseedstruct, status] = se_setseeds(seedstruct,sysid) returns status information indicating when the function does not set a seed.

Tips

• Before invoking this function, load or open the system where you want to set seeds.

Input Arguments

seedstruct	Structure having the same fields as the output of the se_getseeds function: system — Value of the sysid input to se_getseeds seeds — Structure array, of which each element has these fields: block — Path name of a block that uses a random number generator, relative to system value — Numeric seed value of the block
sysid	System name or subsystem path name.

Output Arguments

oldseedstruct	Structure representing original seed values. The form of oldseedstruct is the same as that of seedstruct.
status	Logical array whose nth entry is false if the nth block in seedstruct meets one of these conditions: Does not exist Is not a SimEvents block Does not have a seed parameter in its current configuration
