When a matrix has a shape (5, 9), is it of shape(5, 9) or with shape(5,9)?

As the shape is an attribute of the matrix, I suppose it is with? Or something else e.g. having?

Which one is appropriate?

  1. a matrix of shape (5, 9)
  2. a matrix with shape (5, 9)
  3. a matrix having shape (5, 9)
  4. Else?

This might be on-topic here; it might be on-topic on Mathematics.

One question there indicates that of is acceptable:

Consider a matrix, A, of shape m × n.

However, both the other options are entirely understandable, and grammatical.

    Using with is perfectly acceptable, too, at least going by Mathematics Stackexchange Questions. (And as a mathematician, I can't decide which of these two is better.) Commented Jan 19, 2021 at 12:04
  • Thanks, Peter. By all means as that as an answer.
