Triangular Random Numbers

Create a readable stream for generating pseudorandom numbers drawn from a triangular distribution.

Installation

To use as a general utility, install the CLI package globally

npm install -g @stdlib/random-streams-triangular-cli

Usage

Usage: random-triangular [options] <a> <b> <c>

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.
       --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-triangular 2.0 5.0 4.0 -n 10 --seed 1234
