You can use the GR framework, e.g. srand(0) xd = -2 + 4 * rand(100) yd = -2 + 4 * rand(100) zd = [Float64(xd[i] * exp(-xd[i]^2 - yd[i]^2)) for i = 1:100]
using GR contour(xd, yd, zd, colormap=44) <https://lh3.googleusercontent.com/-2Jv_GQhoJLE/V4CvWwlK5oI/AAAAAAAAADY/dS2YfieTyIEXfUjXoDCNZdnSg0dcevKDwCLcB/s1600/Screen%2BShot%2B2016-07-09%2Bat%2B10.00.51.png> If you only need the gridded data, use the GR gridit function, e.g. (to obtain a 200 x 200 grid): x, y, z = GR.gridit(xd, yd, zd, 200, 200) On Saturday, July 9, 2016 at 12:57:51 AM UTC+2, Kaj Wiik wrote: > > Is there a Julia version of irregularly spaced data gridding that does > zi = griddata(x,y,z,xi,yi), i.e. all arguments are 1d vectors?
