i am running a code on iris recognition using neural network. after simulation of the network, i first of all got a figure 1 which displayed some scattered points in various colour these points represented my number of input variable. after training the network, it was tested and after testing, another figure of scattered points displayed with same colours kinda of clustering together. my question is how do i know the input and output of this network and how do i define what the different colours stand for? the various colours that displays includes red, green, blue and yellow...
thanks

By default scatter3() uses your Z data to determine the color, with the minimum Z value getting the first color in the colormap and the maximum Z value getting the last color in the colormap.

The Z value is the third parameter passed to scatter3()
If you pass 5 parameters or more, the 5th one controls the color.
