Затрудняюсь в переводе выражения “two-way matrix”. Буду весьма признателен за помощь в его переводе на русский язык.

Контекст: «Floristic data recorded in the two-way (quadrat/sample by species/variable) matrix represent multivariate data. Each species/variable or quadrat/sample added to the data-set represents a potential source of variation, and each extra species/variable or quadrat/sample constitutes an additional dimension. The methods for analysing such data are thus techniques for multivariate analysis - multiple quadrats/samples and multiple species (Manly, 2005)».
