Thread Subject: How to generate ROYGBIV Nx3 colormap automatically

I have an Nx10 matrix, and want to plot each row on the same plot, but so that row 1 is red, row N is violet or whatever (that is, each row is a different color, but traversing logically through colorspace).

In other words, the first 'color' for plot will be [1 0 0], and the Nth will be blue/purple.

Is there a function that generates the Nx3 color matrix for this automatically?

The hsv colormap function should work:
hsv(N)

hsv(N) is perfect

Many thanks that's it!
