Astrodynamic / Matrix-in-C

This is a C implementation of various matrix operations, including creating, removing, adding, subtracting, multiplying, and comparing matrices. The library provides functions to perform operations such as matrix transposition, determinant, and inverse.

Matrix Library

This project provides a C implementation of various operations with matrices, such as creating, removing, adding, subtracting, multiplying, and comparing matrices.

Build

To build the project, run the following command:

make all

To clean the build artifacts, run the following command:

make clean

Dependencies

This project requires CMake version 3.0 or higher and a C99-compatible compiler.

Matrix operations

All operations (except matrix comparison) should return the resulting code:

• 0 - OK
• 1 - Error, incorrect matrix
• 2 - Calculation error (mismatched matrix sizes; matrix for which calculations cannot be performed, etc.)

int castom_create_matrix(int rows, int columns, matrix_t *result);
void castom_remove_matrix(matrix_t *A);

#define SUCCESS 1
#define FAILURE 0

int castom_eq_matrix(matrix_t *A, matrix_t *B);

int castom_sum_matrix(matrix_t *A, matrix_t *B, matrix_t *result);
int castom_sub_matrix(matrix_t *A, matrix_t *B, matrix_t *result);
int castom_mult_number(matrix_t *A, double number, matrix_t *result);
int castom_mult_matrix(matrix_t *A, matrix_t *B, matrix_t *result);
int castom_transpose(matrix_t *A, matrix_t *result);
int castom_calc_complements(matrix_t *A, matrix_t *result);
int castom_determinant(matrix_t *A, double *result);
int castom_inverse_matrix(matrix_t *A, matrix_t *result);

Usage Examples

Here's an example of how to use the library to create and add two matrices:

#include <stdio.h>
#include "matrix.h"

int main() {
    matrix_t A, B, C;
    castom_create_matrix(3, 3, &A);
    castom_create_matrix(3, 3, &B);
    castom_create_matrix(3, 3, &C);

    for (int i = 0; i < A.rows; i++) {
        for (int j = 0; j < A.columns; j++) {
            A.matrix[i][j] = i * A.columns + j + 1;
            B.matrix[i][j] = i * A.columns + j + 1;
        }
    }

    castom_sum_matrix(&A, &B, &C);

    for (int i = 0; i < C.rows; i++) {
        for (int j = 0; j < C.columns; j++) {
            printf("%lf ", C.matrix[i][j]);
        }
        printf("\n");
    }

    castom_remove_matrix(&A);
    castom_remove_matrix(&B);
    castom_remove_matrix(&C);
    return 0;
}
