MATLAB: Plot variables (total could cover) from Netcdf file

Data Acquisition Toolboxjonas damsbokssv

Hello ,
I'm Student and work on my project but , I faced a problem because i am beginner in MATLAB and analyze data netcdf format , i have to plot meteorological variables as a function of time, first i tried to plot it with latitude and longitude but i find error using pcolor and plot . i need help to find the correct script for plotting this variables as a function of 'lon' and 'lat' and also time
this is code i used :
filename='tcdc.nc'
 %Read the header 
ncdisp(filename) 
 ncid=netcdf.open(filename,'NOWRITE')
 %inspect num of dimensions, variables, attributes, unim
 [ndim, nvar, natt, unlim]=netcdf.inq(ncid)
for i=0:nvar-1
 [varname, xtype, dimid, natt]=netcdf.inqVar(ncid,i);
if strcmp(varname,'surf_temp')==1 
varnumber=i; end 
end 
[varname, xtype, dimid, natt]=netcdf.inqVar(ncid,varnumber)
 %extract info for each dimension
 for i=1:length(dimid) 
[dimname, dimlength]=netcdf.inqDim(ncid,dimid(1,i))
 end
 for i=0:nvar-1 
[varname, xtype, dimid, natt]=netcdf.inqVar(ncid,i);
 if strcmp(varname,'latitude')==1
 dimnumber=i 
end 
end 
latitude=ncread(filename,'lat') 
longitude=ncread(filename,'lon') 
tcdc=ncread(filename,'tcdc')
pcolor(longitude,latitude,tcdc')
Error using '
Transpose on ND array is not defined. Use PERMUTE
instead.
>> hold on
>> plot(longitude,latitude,tcdc)
Error using plot
Vectors must be the same length
thank you

Your tcdc is a 3D matrix. You can plot only one 2D matrix using pcolor. Follow the below:
pcolor(longitude,latitude,tcdc(:,:,1)')  % plot the first matrix 
[m,n,p] = size(tcdc) ; 
for i = 1:p
    pcolor(longitude,latitude,tcdc(:,:,i)')
    shading interp 
    colorbar
    drawnow
end
