sprandn

Sparse standard-normal random matrix.

Syntax

S = sprandn(m, n, density)
S = sprandn(m, n, density, rc)
S = sprandn(A)

Description

Same shape conventions as sprand, but draws non-zero entries from the standard normal distribution N(0, 1) instead of uniform.

Example

sprandn(50, 50, 0.1)     % 50×50 sparse, ~250 N(0,1) entries
