%LLADO2022_EVALUATENN evaluate the neural network
%   Usage: [y_est] = llado2022_evaluatenn(x_test,NN_pretrained)
%
%   Input parameters:
%     x_test             : Features of the test subset
%     NN_pretrained      : Pretrained network
%     hiddenLayerSize    : Size of the hidden layer
%
%   Output parameters:
%     y_est              : Estimated data
%
%   LLADO2022_EVALUATENN gives the estimation uncertainty of the neural
%   network
