稀疏矩阵(Sparse Matrix)是一种特殊的矩阵,其中大部分元素都是零。与之相对的是稠密矩阵(Dense Matri...
In MATLAB, you can create a sparse matrix using the sparse function. This function allows you to specify the non-zero values and their corresponding row and column indices. The sparse function automatically converts the non-zero elements of the dense matrix into a sparse format while omitting ...
Sparse Matrix Operations Reordering, factoring, and computing with sparse matrices. Iterative Methods for Linear Systems One of the most important and common applications of numerical linear algebra is the solution of linear systems that can be expressed in the formA*x = b. ...

其稀疏矩阵可以表示为CSR(RowMajor)和CSC(ColMajor)格式,eigen数据与matlab数据很好转化。 下列EigenDense2SparseD(double类型)、EigenDense2SparseZ(complex<double>类型)。(使用vs编译作为编译器,mingw编译complex头文件出问题)。matlab 数据转为eigen 数据具体方法见EigenDense2SparseD.cpp和EigenDense2SparseZ.cpp。

稀疏矩阵的生成sparse(A):将A矩阵转化为稀疏矩阵储存方式,如果A矩阵已经是稀疏矩阵,则返回A本身 sparse(m,n):生成一个m MATLAB之稀疏矩阵 部。 说明:M_full和M_sparse其实是同一个矩阵,但是内存却相差了一万倍,可怕。 2、稀疏矩阵的创建MATLAB不会自己创建稀疏矩阵。一般由用户根据商来确定是否要采用稀疏矩阵...
