Deploy classification learner model

Hello,

Using 'Claassification Trainer', I crated a model called 'trainedModel'

I want to predict survival 'c' for the data on the file 'for_prediction.xlsx'

I wrote the following code:

T = readtable('for_prediction.xlsxv');

predictions = trainedModel.predictFcn(T);

T.predictions = predictions;

However, I am getting errors.

I also tried:

>> % This function takes "ValidationData" as an input from Excel and

% returns "yfit" which a prediction based on the "trainedModel" from "model.mat"

function yfit = runModelFromMATLAB(ValidationData)

%#function ClassificationTree % declares which "predict" function to use

load trainedModel.mat; % trained model from Classification Learners App

for_prediction.xlsx = ValidationData;

% convert data to table

ModTableData = cell2table(for_prediction.xlsx, 'VariableNames',...

{'PCLASS','AGE','SIBSP','PARCH',...

'FARE'});

% get classification tree from the model and call predict using this tree

ModelClassTree = trainedModel.ClassificationTree;

yfit = predict(ModelClassTree, ModTableData);

yfit = {char(yfit)};

function yfit = runModelFromMATLAB(ValidationData)

Error: Function definition not supported in this context. Create functions in code file.

Would appreciate any advice. Thanks in advance!
