Subject: Colormapping Matrix with 99-90% zeros and several peaks
I have a Matrix with values ranging from 0 to 2*pi, size of this matrix is 2000² (just as a reference) and there are very few values in there (a maximum of 2*32²).
Now i need a method or an idea to visualize this. What I have so far:
Of course Finding those pixels is hard and they aren't a very good representation.
So my thougth was to make a convolution of the matrix with a 2D-gaussian curve (curve beeing normed at maximum to 1).
But that seems a very crude methode and I have to use this a lot.
Furthermore I'd like it to exclude all zeros ( colormap from white (0) to blue(lowest) to red (highest)).
I really hope for some ideas or usefull matlab methods.
Thanks in advance
