ncwrite error dimension does not have an associated length specified

Hi I got a problem to use ncwrite

Since I want to create a ncfile with lon(313), lat(409), time(3) and climate data. Example below

And got this error

Error using internal.matlab.imagesci.nc/createDimension

'longitude' does not have an associated length specified.

Error in internal.matlab.imagesci.nc/createDimensions (line 289)

this.createDimension(defgid, ...

Error in internal.matlab.imagesci.nc/createVariable (line 422)

this.createDimensions(groupName, dimensions);

Error in nccreate (line 170)

ncObj.createVariable(varName, varargin{:})

climate=rand(313,409,3);
lonn=rand(313,1);
latt=rand(409,1);
time=rand(3,1);

fileout='climate3.nc';
nccreate(fileout,'time','Dimensions',{'time',1,nz},'Datatype', 'double') ;
ncwrite(fileout,'time',time);


nccreate(fileout,'latitude','Dimensions',{'lat',1,ny},'Datatype', 'single') 
ncwrite(fileout,'latitude',latt);


nccreate(fileout,'longitude','Dimensions',{'lon',1,nx},'Datatype', 'single');
ncwrite(fileout,'longitude',lonn);


nccreate(fileout,'climate','Dimensions',{'longitude','latitude','time'}) ;     
ncwrite(fileout,'climate',climate) ;

ny = 409;
nz = 3;
nx = 313;
climate=rand(nx,ny,nz);
lonn=rand(nx,1);
latt=rand(ny,1);
time=rand(nz,1);

fileout='climate3.nc';
nccreate(fileout,'time','Dimensions',{'time',1,nz},'Datatype', 'double') ;
ncwrite(fileout,'time',time);


nccreate(fileout,'latitude','Dimensions',{'lat',1,ny},'Datatype', 'single') 
ncwrite(fileout,'latitude',latt);


nccreate(fileout,'longitude','Dimensions',{'lon',1,nx},'Datatype', 'single');
ncwrite(fileout,'longitude',lonn);

nccreate(fileout,'climate','Dimensions',{'lon','lat','time'}) ;     
ncwrite(fileout,'climate',climate) ;    

info = ncinfo(fileout)

info = struct with fields:
      Filename: '/users/mss.system.gUdGvX/climate3.nc'
          Name: '/'
    Dimensions: [1×3 struct]
     Variables: [1×4 struct]
    Attributes: []
        Groups: []
        Format: 'netcdf4_classic'
     Datatypes: []

{info.Variables.Name}

ans = 1×4 cell array
    {'time'}    {'latitude'}    {'longitude'}    {'climate'}

dims = info.Variables(4).Dimensions;
{dims.Name}

ans = 1×3 cell array
    {'lon'}    {'lat'}    {'time'}

{dims.Length}

ans = 1×3 cell array
    {[313]}    {[409]}    {[3]}
