a rectangular array of elements (or entries) set out by rows and columns
- Our printing-house often wanted sorts, and there was no letter-founder in America; I had seen types cast at James's in London, but without much attention to the manner; however, I now contrived a mould, made use of the letters we had as puncheons, struck the matrices in lead, And thus supply'd in a pretty tolerable way all deficiencies.
There are no more uses of "matrix" in The Autobiography of Benjamin Franklin.
