Incompatibility with Iterator and ArrayAccess interfaces

[fudgelabs]

Using PHP version 8.1.0, it looks as though the Vector class is no longer compatible with the Iterator and ArrayAccess interfaces. I think the incompatibility is solely due to unspecified return types (see errors below -received when instantiating a Vector in a test).

I can add the return types myself, but thought maybe someone else may want to know.

Deprecated: Return type of MathPHP\LinearAlgebra\Vector::current() should either be compatible with Iterator::current(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /home/vagrant/matrixstiffness_v0.3/vendor/markrogoyski/math-php/src/LinearAlgebra/Vector.php on line 807

Deprecated: Return type of MathPHP\LinearAlgebra\Vector::key() should either be compatible with Iterator::key(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /.../vendor/markrogoyski/math-php/src/LinearAlgebra/Vector.php on line 812

Deprecated: Return type of MathPHP\LinearAlgebra\Vector::offsetGet($i) should either be compatible with ArrayAccess::offsetGet(mixed $offset): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /.../vendor/markrogoyski/math-php/src/LinearAlgebra/Vector.php on line 762

Deprecated: Return type of MathPHP\LinearAlgebra\Vector::offsetSet($i, $value) should either be compatible with ArrayAccess::offsetSet(mixed $offset, mixed $value): void, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /.../vendor/markrogoyski/math-php/src/LinearAlgebra/Vector.php on line 772

Deprecated: Return type of MathPHP\LinearAlgebra\Vector::offsetUnset($i) should either be compatible with ArrayAccess::offsetUnset(mixed $offset): void, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /.../vendor/markrogoyski/math-php/src/LinearAlgebra/Vector.php on line 781

Hi @fudgelabs

Thank you for your interest in MathPHP and reporting this issue. This has been addressed in the latest release v2.6.0, as well as some other PHP 8.1 compatibility issues.

Thanks again for the feedback and helping to improve MathPHP.
