How to multiply two matrices in UCINET

In the command line interface (CLI) you use the product command. For example:

->tdavis = transpose(davis)

->women = product(davis tdavis)

->dsp women

Alternatively, you could combine the transpose command with the product, as in:

->women = prod(transp(davis) davis)

Even easier is the xtx command, which is also faster and more memory efficient:

->women = xtx(davis)

If the filenames have spaces or other punctuation, you must enclose them in quotes, as follows:

->output = prod("first matrix" "second matrix")

Note that if the datasets contain parentheses in their names, even quotes won't help. Instead you have do something like this:

->x1 = “collaboration (respondents only)”

->y = prod(x1 "work flow")

There is no menu way to multiply matrices.
