1. Sparse Matrices in MATLAB*P
Stu Blair

2. Objectives – Provide Sparse Matrix Functionality
Sparse Matrix Constructors
Provide Ability to Transfer Sparse Matrices to/from Server
Simple Arithmetic
Numerical Algorithm utilizing simple arithmetic

3. Constructors Provided
A = sparse(M,N*p)
A = sprandn(M,N*p,density)
A = sprand(M,N*p,density)
A = speye(M,N*p)

4. Sparse Matrix Transfer
S = matlab2pp(A);
L = pp2matlab(S);

5. Matrix Manipulation
A = spones(B);
D = full(S);

6. Information
I = nnz(A);

7. Arithmetic
S3 = S1 + S2
S3 = S1 – S2

8. Arithmetic: S = A + B

9. Quick Demo….
