- StringMethods.edit_distance_matrix() SeriesOrIndex #
Computes the edit distance between strings in the series.
The series to compute the matrix should have more than 2 strings and should not contain nulls.
Edit distance is measured based on the Levenshtein edit distance algorithm.
- Series of ListDtype(int64)
Assume N is the length of this series. The return series contains N lists of size N, where the `j`th number in the `i`th row of the series tells the edit distance between the `i`th string and the `j`th string of this series. The matrix is symmetric. Diagonal elements are 0.
