Question

i want to generate normally distributed random data matrices. Are there any java or related functions available for implementing this.

Answer 1

This is built into the standard libraries.

Use Random.nextGaussian() defined here.

This returns a floating-point number for a normal distribution with mean 0.0 and standard deviation 1.0.

If you need a random number from a distribution of mean m and standard deviation s, use this expression:

( Random.nextGaussian() * s ) + m
