# linspace function Null safety

Array linspace(
1. double start,
2. double stop,
3. {int num = 50,
4. bool endpoint = true}
)

Return evenly spaced numbers over a specified interval. Returns `num` evenly spaced samples, calculated over the interval ``start`, `stop``.

# Parameters

• `start` : double The starting value of the sequence.
• `stop` : double The end value of the sequence, unless `endpoint` is set to False. In that case, the sequence consists of all but the last of `num + 1` evenly spaced samples, so that `stop` is excluded. Note that the step size changes when `endpoint` is false.
• `num` : int, optional Number of samples to generate. Default is 50. Must be non-negative.
• `endpoint` : bool, optional If true, `stop` is the last sample. Otherwise, it is not included. Default is True.

# Returns

samples : Array There are `num` equally spaced samples in the closed interval `[start, stop]` or the half-open interval `[start, stop)` (depending on whether `endpoint` is True or False).

• arange : Similar to `linspace`, but uses a step size (instead of the number of samples).

# Examples

``````import 'package:scidart/src/numdart/numdart.dart';

print(linspace(2.0, 3.0, num: 5));
print(linspace(2.0, 3.0, num: 5, endpoint: false));

/* output:
