I have created a struct where the first bit is just a name, and the second bit is a bunch of data

I want to get the data out of the struct so I can manipulate it and put it into a table or an array

Extract the data using the structurename.fieldname syntax. See here: https://www.mathworks.com/help/matlab/matlab_prog/create-a-structure-array.html

% create the structure
patient.test = [79 75 73; 180 178 177.5; 220 210 205]
patient = struct with fields:
    test: [3×3 double]
% Extract the data
data = patient.test
data = 3×3
   79.0000   75.0000   73.0000
  180.0000  178.0000  177.5000
  220.0000  210.0000  205.0000
