Mapping Vectors
- by Dan Snyder
Is there a good way to map vectors? Here's an example of what I mean:
vec0 = [0,0,0,0,0,0,0,0,0,0,0]
vec1 = [1,4,2,7,3,2]
vec2 = [0,0,0,0,0,0,0,0,0]
vec2 = [7,2,7,9,9,6,1,0,4]
vec4 = [0,0,0,0,0,0]
mainvec =
[0,0,0,0,0,0,0,0,0,0,0,1,4,2,7,3,2,0,0,0,0,0,0,0,0,0,7,2,7,9,9,6,1,0,4,0,0,0,0,0,0]
Lets say mainvec doesn't exist (I'm just showing it to you so you can see the general data structure in mind.
Now say I want mainvec(12) which would be 4. Is there a good way to map the call of these vectors without just stitching them together into a mainvec? I realize I could make a bunch of if statements that test the index of mainvec and I can then offset each call depending on where the call is within one of the vectors, so for instance:
mainvec(12) = vec1(1)
which I could do by:
mainvec(index)
if (index >=13)
vect1(index-11);
I wonder if there's a concise way of doing this without if statements. Any Ideas?
