初始化一个 二维vector,行M,列N(行列数确定且含有初始值): 代码语言:javascript 复制 // 初始化一个 二维的matrix, 行M,列N,且值为0vector<vector<int>>matrix(M,vector<int>(N));//等价于下面的vector<vector<int>>matrix(M);for(int i=0;i<M;i++){matrix[i].resize(N);}//等价于下面的vec...
Matrix operations During the development of the vectorial operations, we realized that matrix operations would be needed soon, which shall also benefit from the same UoM validation. The main difficulty was that not all operations were available for any matrices. For example, an operation like the...
