The function "fitMann" is used to estimate the parameters of the uniform shear model [1] in the least-square sense. As an example, the fitting algorithm is applied to the Great Belt dataset used by Mann [1] and the Kaimal spectral model [2,3]. The present Matlab implementation was applied for offshore wind data [4] and simultaneously fit the three parameters of the uniform shear model.

The submission contains:
- the function fitMann.m
- An interactive example file Example.mlx
- a data file greatbeltData that contains digitalized spectral estimate from the Great belt experiment
- The function mannTurb.m introduced in [5]

This is the first version of the submission. Several changes may occur soon. Any comment, suggestion or question is welcomed.
