• This is an example script for using all of the tools in this toolbox
• Can be used as a single command method for viewing beam velocities and ENU velocities regardless of sampling format
• After loading a specified .mat file, this script runs all of the functions in the toolbox in the following order:

GatherData

• Pulls relevant data from the loaded .mat file
• Determines the sampling format (burst/average, beams utilized, multiplexing, bottom tracking, etc) and combines everything into a simplified data structure

ViewBeamData

• Requires data structure formatted as in GatherData
• Creates a plot of beam data, adjusting for the # of beams utilized
• User can select whether to plot beam velocities, echo amplitudes, and/or correlations
• User can also set it to remove bottom tracked velocity from each beam

FillBeams

• Requires data structure formatted as in GatherData
• Primary purpose of this function is to calculate values for beams that were turned off during data collection (by assuming zero error velocity)
• Should also be able to handle data masked over discrete portions of time/space, but this functionality has not been thoroughly tested
• User selects whether to use beam 5 for Z-matching (necessary if two side beams are turned off) or conduct a standard 3-beam solution

B2Erotation This is a work in progress, but is operable with the functionality currently included

• Requires data structure formatted as in GatherData
• Rotates velocities from beam coordinates to Earth coordinates
• User designates weight of beam 5 in calculating vertical velocities
• User selects whether or not to remove ship velocity by subtracting bottom tracked velocity
• *future functionality: User selects whether or not to remove ship velocity by subtracting velocity from GPS
• *future functionality: User selects whether to use internal heading or GPS heading

ViewUVW

• Requires data structure formatted as in GatherData with enu field as added by B2Erotation
• Creates a plot of three components of velocity in Earth coordinates as well as error velocity

To add: function to view echo sounder data (and modify GatherData to pull this info)
