Accessing data within a structure

Hi,

I am using biomechanical data from Vicon. I have used the toolbox btk to get the various parameteres recorded by vicon stored in c3d files into seperate structures. However, I am unsure how to get the data I would like to analyse. For example there is 1x1 structure labelled angle:

Within the structure angles there are various data fields:

How do I access these various fields independantly?

For example how to I get the LKneeAngle from the structure Angles and to be able to plot the third column of data within this data field?

I have tried using getfield but that is not working:

Leftkneeangles = getfield('angles','angles.LKneeAngles');

Thanks for all your help in advance.
