This project implements a matrix operations library (s21_matrix_oop.h) in C++, providing a versatile set of functionalities for matrix manipulation. The library includes a S21Matrix class, implementing various matrix operations, constructors, destructors, and operator overloads.
The S21Matrix class supports the following matrix operations:
| Operation | Description | Exceptional Situations |
|---|---|---|
bool eq_matrix(const S21Matrix& other) |
Checks matrices for equality | |
void sum_matrix(const S21Matrix& other) |
Adds the second matrix to the current one | Different matrix dimensions |
void sub_matrix(const S21Matrix& other) |
Subtracts another matrix from the current one | Different matrix dimensions |
void mul_number(const double num) |
Multiplies the current matrix by a number | |
void mul_matrix(const S21Matrix& other) |
Multiplies the current matrix by the second matrix | Columns of the first matrix not equal to rows of the second matrix |
S21Matrix transpose() |
Creates a new transposed matrix from the current one | |
S21Matrix calc_complements() |
Calculates the algebraic addition matrix of the current one | Matrix is not square |
double determinant() |
Calculates and returns the determinant of the current matrix | Matrix is not square |
S21Matrix inverse_matrix() |
Calculates and returns the inverse matrix | Matrix determinant is 0 |
The S21Matrix class includes the following constructors and destructors:
| Method | Description |
|---|---|
S21Matrix() |
Basic constructor, initializes a matrix of predefined dimensions |
S21Matrix(int rows, int cols) |
Parametrized constructor with the number of rows and columns |
S21Matrix(const S21Matrix& other) |
Copy constructor |
S21Matrix(S21Matrix&& other) |
Move constructor |
~S21Matrix() |
Destructor |
The following operators are overloaded to support various matrix operations:
| Operator | Description | Exceptional Situations |
|---|---|---|
+ |
Matrix addition | Different matrix dimensions |
- |
Matrix subtraction | Different matrix dimensions |
* |
Matrix multiplication and matrix multiplication by a number | Columns of the first matrix not equal to rows of the second matrix |
== |
Checks for matrices equality (eq_matrix) |
|
= |
Assignment of values from one matrix to another | |
+= |
Addition assignment (sum_matrix) |
Different matrix dimensions |
-= |
Difference assignment (sub_matrix) |
Different matrix dimensions |
*= |
Multiplication assignment (mul_matrix/mul_number) |
Columns of the first matrix not equal to rows of the second matrix |
(int i, int j) |
Indexation by matrix elements (row, column) | Index outside the matrix |
- Developed in C++ using the C++17 standard with the GCC compiler.
- Code is organized within the
srcfolder. - Private fields
matrix,rows, andcolumnsare utilized for implementation. - Access to private fields is achieved through accessor and mutator methods.
- Implemented as a static library with the
s21_matrix_oop.hheader file. - Comprehensive unit tests provided using the GTest library.
- A Makefile is included for building the library and running tests, with targets
all,clean,test,s21_matrix_oop.a.
To build the library and run tests, use the provided Makefile with the following goals:
make all # Build the library
make clean # Clean the project files
make test # Run tests
