10 PEAR classes that are familiar with PHP processing complex mathematical titles

The Fibonacci sequence is a connected sequence number, which was first invented by an Italian math. This class provides a method for calculating one or several sequence members. the use of pseudo-random numbers such as native devices, visual arts and music usually requires such control. It can also be used to check whether an integer belongs to the feberatch sequence.

If you have a background in mathematics, you may have realized that PHP does not have special functions for processing advanced mathematical concepts-complex numbers, scores, polynomials, statistical data, and matrices.

However, this disadvantage can be compensated by PEAR and PHP expansion and utilization libraries, which provide a large number of ready-made data packets for processing complex mathematical units. These packages provide a robust, well-tested code library for application developers, while helping you economically structure the time and effort required for your own mathematical algorithms.

This article lists the 10 PEAR data packets that developers are particularly interested in when handling complex mathematical titles in their projects (Table ). Check and try-you may not know, you may find a solution for the title you are currently facing

This class can be applied when you need to calculate and process the Fibonacci number.

Math_Vector

This class provides an object-oriented framework for processing vectors. It supports important vector calculation, such as the interval between the calculation vectors (Cartell, Manhattan and the board); reverse, transformation, scaling and normalization vector; and the length and value of the calculation vector.

 

This class is used when two-dimensional or three-dimensional space needs to perform vector calculation.

Math_BinaryUtils

This class provides a framework for processing binary data, including conversion between large-byte, small-byte, decimal, integer, and hexadecimal patterns; packaging and opening options; and easy addition and subtraction of binary numbers.

 

This class is applied when binary numbers are required.

Math_Stats

This class provides a set of practical functions for changing a dataset for statistical analysis. Its function includes calculating the average value (scale, internal four sub-location, coordination, ry), the value and the number of values; find out the scale, do the best and the internal four sub-location difference; calculate the coefficient of variation, the original moment and the skew and peak state of the calculation and distribution.

 

This class is applied when you need to perform quick basic statistical analysis on a dataset.

Math_Histogram

This class classifies a digital data aggregation and depicts a graphical frequency scatter chart to perform statistical analysis. It defines a box, allocates data points to the box, and generates a histogram dataset scatter chart in two or three dimensions using numbers or graphs.

 

The application of this class knows the frequency of the distribution of a dataset.

Clarification

Math_Complex

This class allows you to perform basic advanced arithmetic operations on complex numbers (including real numbers and virtual numbers. It contains an object-oriented interface that supports triangle and logarithm operations on these numbers.

 

This class is applied when performing triangle, hyperbolic, or exponential operations on complex numbers.

Math_Fraction

This class promises you to treat the numerator and denominator of the score as the independent variable of the class, so that you can naturally "score object ". It contains the method of adding, subtraction, multiplication, division, and reciprocal of scores. It can also compare two or more scores to find the maximum value.

 

This class is used when PHP needs to process numeric values.

Math_Derivative

Derivative refers to the change rate of an independent variable corresponding to a specified function. it is one of the most important concepts in calculus. This class provides an object-oriented framework to find the derivative of any mathematical expression to a specified extent. It supports basic calculation rules (addition, subtraction, multiplication, division) and a cache for accelerated derivation.

 

Apply this class when processing the derivative.

Math_Polynomial

Polynomials are composed of several expressions, and the exponent of each independent variable is different. This class provides a variety of tools to solve the polynomial equations, including the basic arithmetic operation of the polynomial, the derivative and the number of times of the polynomial, and the value of the polynomial in the independent variable to take a specific value.

 

Use this class to simplify complex polynomial equations.

Math_Matrix

This class provides an object-oriented framework to complete arithmetic operations on the inclusion matrix. At this time, the matrix is represented by a series of arrays. this class is used to add, subtract, multiply, and divide these arrays. it is determined whether the array is square. an important matrix value is calculated, such as the deciding factor and model.

 

Apply this class when you need to process the digital matrix.

Math_Fibonacci

The Fibonacci sequence is a connected sequence number, which was first invented by an Italian math. This class provides a method for calculating one or several sequence members. the use of pseudo-random numbers such as native devices, visual arts and music usually requires such control. It can also be used to check whether an integer belongs to the feberatch sequence.
