# NTRANDCHI

Returns chi pseudo random number(s) based on Mersenne Twister Algorithm which has long period (2^{19937}-1), high order of equidistribution and 623 dimensions.

## Syntax

**NTRANDCHI**(

*Size,**N,**Algorithm,**Random seed1,**Random seed2*

)

#### Parameters

is # of random numbers (Positive integer).**Size**is a parameter of the distribution (Positive integer).**N**is a integer value that determines a method to generate uniform random number.**Algorithm**- 0: Mersenne Twister(2002)
- 1: Mersenne Twister(1998)
- 2: Numerical Recipesran2()

is 1st. random seed.**Random seed1**is 2nd. random seed.**Random seed2**

## Remarks

- The distribution has a semi-infinite support .
