lognrnd (Statistics Toolbox)

Random matrices from the lognormal distribution

Syntax

R = lognrnd(MU,SIGMA)
R = lognrnd(MU,SIGMA,m)
R = lognrnd(MU,SIGMA,m,n)

Description

R = lognrnd(MU,SIGMA) generates lognormal random numbers with parameters MU and SIGMA. Vector or matrix inputs for MU and SIGMA must have the same size, which is also the size of R. A scalar input for MU or SIGMA is expanded to a constant matrix with the same dimensions as the other input.

R = lognrnd(MU,SIGMA,m) generates lognormal random numbers with parameters MU and SIGMA, where m is a 1-by-2 vector that contains the row and column dimensions of R.

R = lognrnd(MU,SIGMA,m,n) generates lognormal random numbers with parameters MU and SIGMA, where scalars m and n are the row and column dimensions of R.

Example

r = lognrnd(0,1,4,3)
r =
    3.2058    0.4983    1.3022
    1.8717    5.4529    2.3909
    1.0780    1.0608    0.2355
    1.4213    6.0320    0.4960
