numda #

A numeric library for dart (just like numpy)

example #

File: complex1.dart

import 'package:numda/numda.dart';

main() {
  var a = Complex(1,2); // , b = c(1,1);
  var b = Complex.parse("1-1i");
  print("a=$a");
  print("b=$b");
  print("a+b=${a+b}");
  print("a-b=${a-b}");
  print("a*b=${a*b}");
  print("a/b=${a/b}");
  print("a.exp()=${a.exp()}");
  print("a.log()=${a.log()}");
  print("a.log().str(4)=${a.log().str(4)}");
}

run:

$ dart complex1.dart        
a=1.0+2.0i
b=1.0-1.0i
a+b=2.0+1.0i
a-b=0.0+3.0i
a*b=3.0+1.0i
a/b=-0.5+1.5i
a.exp()=-1.1312043837568135+2.4717266720048188i
a.log()=0.8047189562170501+1.1071487177940904i
a.log().str(4)=0.8047+1.1071i
