Problem with initialization bim's ready example in Octave - octave

Question

On assignment, they gave me a step-by-step example from this article http://wiki.octave.org/Bim_package.
The example was typed manually, without copy-paste.I already install this packages- fpl, bim,msh, image.
Octave example:
pkg load bim
pkg load msh
pkg load fpl
[mesh]=msh2m_gmsh("fuime","scale",1,"clscale",.1); – Error
[mesh]=bim2c_mesh_properties(mesh);
pdemesh(mesh.p,mesh.e,mesh.t);
view(2)
xu=mesh.p(1,:).';
yu=mesh.p(2,:).';
nelems=columns(mesh.t);
nnodes=columns(mesh.p);
epsilon=.1;
phi=xu+yu;
AdvDiff=bim2a_advaction_diffusion(mesh,epsilon,1,1,phi);
Mass=bim2a_reaction(mesh,1,1);
b=bim2a_rhs(mesh,f,g);
A=AdvDiff+Mass;
GammaD=bim2c_unknowns_on_side(mesh,[1 2]);
GammaN=bim2c_unknowns_on_side(mesh,[3 4]);
GammaN=setdiff(GammaN,GammaD);
jn=zeros(length(GammaN),1);
ud=3*xu;
Omega=setdiff(1:nnodes,union(GammaD,GammaN));
Add=A(GammaD,GammaD);
Adn=A(GammaD,GammaN);
Adi=A(GammaD,Omega);
And=A(GammaN,GammaD);
Ann=A(GammaN,GammaN);
Ani=A(GammaN,Omega);
Aid=A(Omega,GammaD);
Ain=A(Omega,GammaN);
Aii=A(Omega,Omega);
bd=b(GammaD);
bn=b(GammaN);
bi=b(Omega);
temp=[Ann Ani;Ain Aii]\[jn+bn-And*ud(GammaD); bi-Aid*ud(GammaD)];
u=ud;
u(GammaN)=temp(1:numel(GammaN));
u(Omega)=temp(length(GammaN)+1:end);
jd=[Add Adi Adn]*u([GammaD;Omega;GammaN])-bd;
[gx,gy]=bim2c_pde_gradient(mesh,u);
[jxglob,jyglob]=bim2c_global_flux(mesh,u,epsilon*ones(nelems,1),ones(nnodes,1),ones(nnodes,1),phi);
fpl_vtk_write_field("vtkdata",mesh,{u,"Solution"},{[gx:gy]',"Gradient"},1);
pdesurf(mesh.p,mesh.t,u);
In this - [mesh]=msh2m_gmsh("fuime","scale",1,"clscale",.1);Error

WHAT HAVE I TAKEN TO FIX THE ERROR
I decided that the problem is in uninstalled packages.
According to the answer I was given in this thread Error,when installing a new package in Octave.
I started to install the package mesh, but here another error came out.
error: get_forge_pkg: package not found: "mesh". Maybe you meant "lssa?"
error: called from
get_forge_pkg at line 90 column 5
get_forge_download at line 32 column 14
pkg at line 500 column 31
But the mesh package not found.The package msh already installed.
How I can fixed my problem?
