Hi Guys.
I've got two Vectors, one has some missing values. After plotting both against each other an creating a linear fit/regression I want to calculate the missing values.
My MATLAB Version is 2017b i think.
Best

% Set the random number generator seed, for reproducibility
rng default
% Make up some pretend data
N = 10;
x = (1:N)';
y = 2*x + 0.3*randn(N,1);
% Make a couple y values missing
missingIndex = [2 7];
y(missingIndex) = NaN;
% Fit the data
mdl = fitlm(x,y)
% Get the predicted values for the missing y values
y_missing_predicted = predict(mdl,x(missingIndex))
