3.1.5.1. agetmat output variablesΒΆ

  1. These are the most useful variables in the processed 5-minute averages:

data =
        dday: [1x1436 double]         zero-based UTC decimal day
         lon: [1x1436 double]         decimal longitude
         lat: [1x1436 double]         decimal latitude
     heading: [1x1436 double]         original heading, likely a gyro

        bins: [1x50 double]           bins (for convenience)
           z: [50x1 double]           nominal vertical depth (same as 'depth')
     uabs_sm: [50x1436 double]        --\  ocean velocity in earth coords
     vabs_sm: [50x1436 double]        --/  using smoothed navigation
