Image set Walsh spectra of 3-ary Boolean functions; families (two matrices)

The matrix on the left is the family matrix of Boolean function in its top row.
The number rows on the right are the corresponding Walsh spectra. They differ only in their signs.
The distribution of signs corresponds to the pattern of a Walsh matrix.
It is highlighted in red, where it corresponds to the binary Walsh spectrum — otherwise in blue.
