Vectors must be the same length.
Error in NAEAllSources (line 522)
plot(t,smooth(data),'linewidth',2). Code is given below:

The number of x and y values must be same. Change the time-vector to
t=1:numel(data);

Or if you know your data is real and you want the X coordinates to be 1:numel(data) you can just call plot with one data input.
plot((1:10).^2, 'o-', 'LineWidth', 2) % Uses x = 1:10
