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. The size of R is the common size of MU and SIGMA if both are matrices. If either parameter is a scalar, the size of R is the size of the other parameter.

R = lognrnd(MU,SIGMA,m) generates lognormal random numbers with parameters MU and SIGMA. 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. The 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
