Plot netcdf map file with pcolor

I'm trying to plot a matrix with temperature values ​​with 5450x5450 using pcolor.

This temperature matrix comes from a netcdf file from the GOES-16 satellite.

With it also comes a matrix of longitudes and one of latitudes of the same dimension.

I Tried:

s = pcolor(arrayLonFullDisk, arrayLatFullDisk,arrayTempFullDisk); 
s.FaceColor = 'interp'; 
colormap(jet); 

But I only have an all black graphic as an answer.

s = pcolor(arrayLonFullDisk, arrayLatFullDisk,arrayTempFullDisk); 
shading interp 
colormap(jet);
