when is sepcify the mean, standard deviation and the matrix size, i
get the following message
Undefined function or method 'lognrnd' for input arguments of type

What version are you using?

For example the following works for me:

lognrnd(10,.2,7,9)


Ah -- lognrnd() is part of the Statistics Toolbox. Do you have that
installed?
