Sparse matrices provide efficient storage of double or logical data that has a large percentage of zeros. While full (or dense) matrices store every single element in memory regardless of value, sparse …
Sparse Matrix Operations - MATLAB & Simulink - MathWorks
Sparse Matrix Operations Efficiency of Operations Computational Complexity The computational complexity of sparse operations is proportional to nnz, the number of nonzero elements in the matrix. …
Constructing Sparse Matrices - MATLAB & Simulink - MathWorks
Constructing Sparse Matrices Creating Sparse Matrices MATLAB ® never creates sparse matrices automatically. Instead, you must determine if a matrix contains a large enough percentage of zeros …
sparse - Create sparse matrix - MATLAB - MathWorks
This MATLAB function converts a full matrix into sparse form by squeezing out any zero elements.
spalloc - Allocate space for sparse matrix - MATLAB - MathWorks
This MATLAB function creates an all-zero sparse matrix S of size m-by-n with room to hold nz nonzero elements, where nz >= 1.
Computational Advantages of Sparse Matrices - MATLAB & Simulink
Computational Advantages of Sparse Matrices Memory Management Using sparse matrices to store data that contains a large number of zero-valued elements can both save a significant amount of …
speye - Sparse identity matrix - MATLAB - MathWorks
Description S = speye returns a sparse scalar 1. S = speye(n) returns a sparse n -by- n identity matrix, with ones on the main diagonal and zeros elsewhere.
sprandn - Sparse normally distributed random matrix - MATLAB
This MATLAB function creates a sparse matrix that has the same sparsity pattern as the matrix S, but with normally distributed random entries with mean 0 and variance 1.
sprand - Sparse uniformly distributed random matrix - MATLAB
This MATLAB function creates a sparse matrix that has the same sparsity pattern as the matrix S, but with uniformly distributed random entries.
