randnormal (MathScript RT Module Function)
Owning Class: statistics
Requires: MathScript RT Module
Syntax
randnormal('seed')
randnormal('seed', s)
c = randnormal
d = randnormal('seed')
c = randnormal(a)
c = randnormal(a, b)
c = randnormal([a, b])
Legacy Name: randn
Description
Generates normally distributed pseudorandom numbers. randnormal('seed') returns the seed of the pseudorandom number generator. randnormal('seed', s) sets the seed of the pseudorandom number generator to s. LabVIEW uses this seed to generate a pseudorandom number for the next call to the randnormal function. c = randnormal generates a single pseudorandom number. c = randnormal(a, b) is equivalent to c = randnormal([a, b]).
Inputs
| Name | Description |
|---|---|
| a | Specifies the number of rows in c. a is a positive integer. |
| b | Specifies the number of columns in c. b is a positive integer. |
| s | Specifies the seed of the pseudorandom number generator to use for the next call to the randnormal function. |
Outputs
| Name | Description |
|---|---|
| c | Returns an a-by-b matrix of normally distributed pseudorandom numbers. If you do not specify b, c returns a square matrix of length a. The elements in c have an approximate mean of 0 and an approximate standard deviation of 1. |
| d | Returns the seed of the pseudorandom number generator. |
Examples
A = [3, 4]
C = randnormal(A)
S = randnormal('seed')
X = randnormal(10);
randnormal('seed', S)
Y = randnormal(10);
