sprand

Sparse uniformly distributed random matrix.

📝 Syntax

• R = sprand(S)

• R = sprand(m,n,density)

📥 Input argument

• S - Input matrix

• m - Number of rows

• density - Density of the non-zero elements

📤 Output argument

• S - a sparse matrix.

📄 Description

R = sprand(S) creates a sparse matrix that has the same sparsity pattern as the matrix S, but with uniformly distributed random entries.

R = sprand(m,n,density) creates a random m-by-n sparse matrix with approximately density*m*n uniformly distributed nonzero entries for density in the interval [0,1].

💡 Examples

sprand with matrix pattern

S = [1 0 0; 0 1 0; 0 0 1]; R = sprand(S)

sprand with size and density

R = sprand(5, 5, 0.2)
