Non-graphing calculator supporting complex matrices?

[supernumero]

I am teaching a differential equations course. I allow my students to use a non-graphing calculator in exams.

I just realized that I do not know of *any* current non-graphing calculator that can handle complex matrices (in particular, finding complex eigenvectors of real matrices: if a complex eigenvalue is known, the eigenvector(s) can be found via row operations). I find this state of affairs amazing, given that the HP 15C could do this over 30 years ago, even with its meek 1-line segmented LCD display. Sadly, not even the 34S seems to include the 15C's functions to handle complex matrices via real matrices (I beg to be corrected on this!).

I (and my students) will appreciate any info on this topic.
