Todo List

Member MathPHP::irr (array $values, float $initial_guess=0.1)

: Use eigenvalues to find the roots of a characteristic polynomial. This will allow finding all solutions and eliminate the need of the initial_guess.

Member MathPHP::__construct (int $w, int $n, int $d)

How to handle negative numbers in various positions.

Member MathPHP::primeFactorization (int $n)

Use a better algorithm.

Member MathPHP::getSplinePoints ($source, array $args=[])

Add method to verify function is continuous on our interval

Add method to verify input arguments are valid. Verify $start and $end are numbers, $end > $start, and $points is an integer > 1

Member MathPHP::getPoints ($source, array $args=[])

Add method to verify function is continuous on our interval

Add method to verify input arguments are valid. Verify $start and $end are numbers, $end > $start, and $points is an integer > 1

Member MathPHP::inverse (float $target)

check the parameter ranges.

Member MathPHP::cdf (float $x)

how to handle x = 0, depending on context, some say CDF=.5 @ x=0

Member MathPHP::pdf (float $x)

how to handle x = 0

Member MathPHP::kendallsTau (array $X, array $Y)

Implement with algorithm faster than O(n²)
