Approximate the membership functions by trapezoids forming a Ruspini-like partition
output_i=ApproxOutputTrapezoids(xs,vs,CutLevel,DimNo,m)
Approximate the membership functions by trapezoids forming a Ruspini-like
partition
-------------------------------------------------------------------------
Parameters
-------------------------------------------------------------------------
xs - Column vector containing the data points in ascending order.
vs - Column vector containing the centers of the clusters.
CutLevel - Indicates at which alpha level the shape of the cluster should
be cut for the approximation of the core of the fuzzy set.
DimNo - The number of the current output dimension.
m - Exponent for the calculation of the membership matrix.
-------------------------------------------------------------------------
Returned values
-------------------------------------------------------------------------
output_i - Row vector describing the output linguistic variables.
Each element contains a structure describing one output
dimension.
