MT19937
Create a readable stream for a 32-bit Mersenne Twister pseudorandom number generator.
Installation
To use as a general utility, install the CLI package globally
npm install -g @stdlib/random-streams-mt19937-cli
Usage
Usage: random-mt19937 [options]
Options:
-h, --help Print this message.
-V, --version Print the package version.
--sep sep Separator used to join streamed data. Default: '\n'.
-n, --iter iterations Number of pseudorandom numbers.
--normalized Generate pseudorandom numbers on the interval [0,1).
--seed seed Pseudorandom number generator seed.
--state filepath Path to a file containing the pseudorandom number
generator state.
--snapshot filepath Output file path for saving the pseudorandom number
generator state upon exit.
Notes
- In accordance with POSIX convention, a trailing newline is always appended to generated output prior to exit.
- Specifying a "snapshot" file path is useful when wanting to resume pseudorandom number generation due to, e.g., a downstream failure in an analysis pipeline. Before exiting, the process will store the pseudorandom number generator state in a file specified according to a provided file path. Upon loading a snapshot (state), the process will generate pseudorandom numbers starting from the loaded state, thus avoiding having to seed and replay an entire analysis.
Examples
$ random-mt19937 -n 10 --seed 1234
