• Updated the Flutter demo in the example/ folder

[3.1.1]

• Dependencies versions update
• Added more tests cases
• Updated the Flutter demo in the example/ folder

[3.1.0]

• BREAKING: Now NumericalIntegration requires the function via constructor (earlier it was passed to the integrate() function)

• Added the rank() method on Matrix<T>
• Bug fixes on various matrix operations
• Bug fixes in Algebraic
• Dependencies versions update

• Dependencies versions update
• Minor enhancement in the PolynomialLongDivision class
• Added trace computation on matrices
• Added french localization to the Flutter example app

[2.1.2]

• Dependencies versions update
• Updated example to Flutter 2.2.0 and improved coverage

• Dependencies versions update

[2.1.0]

• Changes on deep copy logic for lists (now the library uses List.from() on immutable objects)
• Added the PolynomialLongDivision class to divide a polynomial by another
• Now the Algebraic type supports opeartor/ too so you can divide polynomials to get quotient and remainder
