Print parameters of classification model

I have trained classification models for which I am writing a result-display function to print information about the trained models

Specifically, I would like to use the for loop to print every parameter name and value pairs

I would like to avoid hardcoding parameter name to do this as I will be displaying results of many different types of classifiers

Below is the simple test script to train a decision tree:

% load dataset
load ionosphere
% train model - decision tree
model = fitctree(X, Y, 'SplitCriterion', 'gdi', 'MaxNumSplits', 100, ...
    'KFold', 5);

I know that model.PadelParameters.LearnerTemplates{1} contains the FitTemplate property with parameter names and corresponding values. Below outputs show the parameters for the model trained above:

>> model.ModelParameters.LearnerTemplates{1,1}

ans = 

Fit template for classification Tree.

        SplitCriterion: 'gdi'
             MinParent: []
               MinLeaf: []
             MaxSplits: 100
          NVarToSample: []
           MergeLeaves: []
                 Prune: []
        PruneCriterion: []
               QEToler: []
            NSurrogate: []
                MaxCat: []
                AlgCat: []
    PredictorSelection: []
          UseChisqTest: []
                Stream: []
          Reproducible: []
               Version: 2
                Method: 'Tree'
                  Type: 'classification'

I would like to create a loop using fprintf to print parameter names and corresponding values for the ones with values without hardcoding the fieldnames. I have tried fieldnames method to see if I could extract field names but it returns empty cell...

Desired output looks like the following for the above test example:

|=======================================================================|
|                        Learner |     Hyperparameter:            Value |
|=======================================================================|
|            classification Tree |     SplitCriterion:            'gdi' |
|                                |          MaxSplits:             100  |
|                                |            Version:               2  |

Is there a method I can use to accomplish this task?

Any help will be greated appreciated!
