Description

The NumDart package allows you to do advanced math with the dart language. The project is the dart language edition of the NumPy package.

Example

import 'package:numdart/numdart.dart' as nd;
void  main(List<String> arguments) {
print(nd.extraction(
[0.7,  0.8], [1.2,  1.7,  19]));  // out: Array [-0.5, -0.8999999999999999]

print(nd.sqrtArray([0.2], [0.1]));  // out: Array [0.4472135954999579]

print(nd.arange(1,  10,  2));  // out: Array [1, 3, 5, 7, 9]

  

// Reshape Method:

nd.Array newArray = nd.arange(0,  40,  5).reshape([4,  2]); // out: [[0, 5, 10, 15], [20, 25, 30, 35]]

print(newArray);  // out: Array [[0, 5, 10, 15], [20, 25, 30, 35]]

print(nd.sin([
nd.pi,
0.5,
7.8,
6.9]));  // Array [1.2246467991473532e-16, 0.479425538604203, 0.998543345374605, 0.5784397643882001]

  

print(nd.arround([0.7,  1.2,  17,  23,  253], sdecimal:  1));  // out: Array [0.0, 0.0, 20.0, 20.0, 250.0]

print(nd.linspace(0,  15,  3));  // out: Array [0.0, 5.0, 10.0, 15.0]

print(nd.array([0,  1,  2,  3,  4,  5,  6]));  // out: Array [0, 1, 2, 3, 4, 5, 6]

print(nd.arround([0,  5,  7,  12,  0.8,  33,  7.8],

decimal:  1));  // out: Array [0.0, 10.0, 10.0, 10.0, 0.0, 30.0, 10.0]	  

print(nd.hypot(3,  4));  // out: 5.0
}
