For instance, I have
x = 2000:0.5:2004; y = 45000:0.3:45009; z = 10:0.2:12;
which are axes of a volume, x has length of 9, y has 31 and z has 11.
Now a volume filled of nan values and given by;
C = rand(9,31,11)*nan;
I want to fill this volume with values when new values come up, it will have x, y, z and the corresponding value. So, I need to find the closest index location and fill the value there. E.g.
x =2002.13, y = 45006.811, z = 11.36 have value of 10000 so i want to fill the corresponding C(x,y,z) = 10000;
here I need to find the index for x = 2002, y = 45006.9, z = 11.4 and fill the value 10000 there in C.
how can I use the values converted to closed index in the volume. Thanks
