编写一个矩阵程序，要求可以运算矩阵的加减乘除，帮帮忙。
具体要求和题目一样，谢谢.....^_^
[解决办法]
线性代数库，blas， lapack， intel mkl ....
开源，商业，各种 线性代数的库。 拿来主义就行了

唉，哥给你写矩阵的加法和减法吧，乘法和除法自己去实现，都不难的(感到难就去翻线代)，共楼主参考：
#include <iostream>using namespace std;class Matrix{private: double* data; int row; int column;public: Matrix(int row, int column) { this->row = row; this->column = column; data = new double[row * column];//(double*)malloc(sizeof(double) * row * column); } double* get_data() { return data; } int get_row() { return row; } int get_column() { return column; } Matrix& ADD(Matrix& matrix) { if((row != matrix.get_row()) || (column != matrix.get_column())) { cout << "Fails to add two matrices with different row or column." << endl; } for(int i = 0; i < row; ++i) { for(int j = 0; j < column; ++j) { *(data + i * column + j) += *(matrix.get_data() + i * column + j); } } return *this; } Matrix& MINUS(Matrix& matrix) { if((row != matrix.get_row()) || (column != matrix.get_column())) { cout << "Fails to minus a matrix with different row or column." << endl; } for(int i = 0; i < row; ++i) { for(int j = 0; j < column; ++j) { *(data + i * column + j) -= *(matrix.get_data() + i * column + j); } } return *this; } void display() { for(int i = 0; i < row; ++i) { for(int j = 0; j < column; ++j) { cout << *(data + i * column + j) << "\t"; } cout << endl; } } ~Matrix() { //free(data); delete[] data; }};int main(int argc, char** argv){ Matrix a(2, 2); for(int i = 0; i < 2; ++i) { for(int j = 0; j < 2; ++j) { *(a.get_data() + i * 2 + j) = 1 + i * 2 + j; } } a.display(); cout << "============" << endl; Matrix b(2, 2); for(int i = 0; i < 2; ++i) { for(int j = 0; j < 2; ++j) { *(b.get_data() + i * 2 + j) = 2 + i * 2 + j; } } b.display(); cout << "============" << endl; //a.ADD(b); //a.display(); //cout << "============" << endl; b.MINUS(a); b.display(); return 0;}
