    2727== Turbulent  statistics ==
    28 From these files, basis turbulence statistics can be provided by the function ''turb_stat.m'' to be selected in the menu '''[Action]''' of '''series''': select the option 'more...' which gives access to a browser from which this function, located in the folder 'UVMAT/series' can be selected. Then run the calculation and visualise the different fields with '''uvmat''', after selection by '''get_field''': for instance the average of V gives the mean jet structure. The field UVmean clearly shows the structure of the Reynolds stress across the jet, positive on one side and negative on the other side, corresponding on the radial eddy diffusion of the jet.

Then click on 'get_field' in '''[Fields]''' in '''series''' (right hand side), a new '''get_field''' GUI pops up. Select 'U' and 'V', click on '''[OK]''' and '''[RUN]''' the calculation in '''series'''.

     30The result automaticaly shows up in '''uvmat''' and another '''get_field''' GUI appears, allowing to select the field coordinates: for instance the average of VMean gives the mean vertical velocity of the jet structure. The field uvMean clearly shows the structure of the Reynolds stress across the jet, if you create a '''[Projection object/line_x]''' on the result image you will clearly see that the curbe is positive on one side and negative on the other side, corresponding on the radial eddy diffusion of the jet.
