There is some overlap between those libraries. However, it does one thing that none of the other JS libraries (from here: http://jster.net/category/math-libraries) really focus on: to support the full complex domain for all the functions.
About numerics vs plotting: They are in different js files, jsmat.js and jsmat_plot.js. The plotting file depends on the numerics one though, as it needs to use its Complex type. The main focus of the package is the numerics, the plotting is a demo, and especially, debugging device.
