add error plot for this code
i want to add error plot for this code.Can you help?
% Load the engine_dataset
load engine_dataset
% Prepare the data
X = engineInputs.';
Y= engineTargets.';
% Split the data into training and testing sets
cv = cvpartition(size(X,1),'HoldOut',0.2);
Xtrain = X(cv.training,:);
Ytrain = Y(cv.training,:);
Xtest = X(cv.test,:);
Ytest = Y(cv.test,:);
% Train the Gradient Boosting model
Model1 = fitrensemble(Xtrain,Ytrain(:,1),'Method','LSBoost','NumLearningCycles',500,'Learners',templateTree('MaxNumSplits',10));
Model2 = fitrensemble(Xtrain,Ytrain(:,2),'Method','LSBoost','NumLearningCycles',500,'Learners',templateTree('MaxNumSplits',10));

time = time';
simin = timeseries(X,time);
simout = timeseries(Y,time);
model = 'SimMdlName_V1';
system_under_design = [model '/Gradient Boost Predict Model'];

open_system(model);
hdlsetup(model);
