Preprocesing tools problem in v2rho_2d.m

[lalvarez]

Hello to All

I´m having this problem while computing geostrophic currents in the v2rho_2d.m
routine

Compute geostrophic currents
time index: 1
Attempted to access var_rho(2,:); index out of bounds because size(var_rho)=[1,0].

Error in v2rho_2d (line 37)
var_rho(1,:)=var_rho(2,:);

Any help is welcome

Thanks
