Invalid data type. First argument must be of type double or single. Breakpoints must be a vector containing sample point values or a logical vector. Polynomial degree must be a non-negative integer scalar. Incorrect number of input arguments. Parameter names and values must occur in pairs. Parameter name must be ''Continuous'' or ''SamplePoints''. ''SamplePoints'' value must be real. ''SamplePoints'' value contains duplicates. ''SamplePoints'' values must be finite. ''SamplePoints'' value must be a double, single, datetime, or duration vector. The number of elements in the ''SamplePoints'' value must equal the size of the first argument along the first dimension. ''SamplePoints'' values must be sorted in ascending order. Sparse ''SamplePoints'' values are not supported. Polynomial is not unique or badly conditioned. Add distinct sample points or reduce the degree of the polynomial. Invalid trend type ''{0}''.
