GaussianNoise(Variable, Variable) Function

 Top 

Description

Returns a random number with a Gaussian probability distribution defined by the specified mean and standard deviation.

 

Note that this function shares its seed value with FreeFlyer's internal random number generation. This means that even with a set seed value it is possible for this function to generate inconsistent values across Mission Plan executions based on the sequence of events undergone in the Mission Plan.

A random number with a Gaussian probability distribution defined by the specified mean and standard deviation.

 

Syntax

myVariable1 = GaussianNoise(myVariable2, myVariable3);

 

 

Example 1

This example creates a plot showing Gaussian noise with a mean of 0 and standard deviation of 1.

 

Variable i;

PlotWindow PW1({GaussianNoise(0, 1), GaussianNoise(0, 1)}, 0);

 

// Show points

PW1.LineType = 1;

PW1.MaxPoints = 100000;

 

For i = 0 to 10000 step 1;

 

 Update PW1;

 

End;

 

 

Output:
