I want to use this function for smoothing and interpolation https://www.mathworks.com/matlabcentral/fileexchange/25634-fast--n-easy-smoothing

ROBUST smoothing Z = SMOOTHN(...,'robust') carries out a robust smoothing that minimizes the influence of outlying data.An iteration process is used with the 'ROBUST' option, or in the presence of weighted and/or missing values. Z = SMOOTHN(...,OPTIONS) smoothes with the termination parameters specified in the structure OPTIONS. OPTIONS is a structure of optional parameters that change the default smoothing properties. It must be last input argument.

The structure OPTIONS can contain the following fields: OPTIONS.TolZ: Termination tolerance on Z (default = 1e-3), OPTIONS.TolZ must be in ]0,1[ OPTIONS.MaxIter: Maximum number of iterations allowed (default = 100) OPTIONS.Initial: Initial value for the iterative process (default = original data, Y) OPTIONS.Weight: Weight function for robust smoothing:'bisquare' (default), 'talworth' or 'cauchy'

How can I use these structure options? How can I include them in the command line?

Thanks for your reply. I do not need another function, I need to know how to write the command line which enables me to use the structure options in the smoothn function
