- array instance. Should have a numeric data type. Must have at least one dimension. If `self` is one-dimensional having shape `(M)` and `other` has more than one dimension, `self` must be promoted to a two-dimensional array by prepending `1` to its dimensions (i.e., must have shape `(1, M)`). After matrix multiplication, the prepended dimensions in the returned array must be removed. If `self` has more than one dimension (including after vector-to-matrix promotion), `self` must be compatible with `other` (see {ref}`broadcasting`). If `self` has shape `(..., M, K)`, the innermost two dimensions form matrices on which to perform matrix multiplication.
