I need to construct a location table from the elements of matrix as below

Turtle Shell Matrix

b = rem(0:255,8);
y=rem(1:255,2);
x=y';
c=cumsum([1;(3 - x)]);
d=bsxfun(@plus,-1:254,c);
f=rem(d,256);
out=b(f+1);

From the matrix shown in fig 'turtleshell matrix', I need to create a location table as shown in fig 'location table' based on the position of pixels present in four locations as shown in fig 'location'.The values in location 1 and location 4 are always {1,3,5,7} and location 2 and location 3 are always {0,2,4,6).

Is it possible to implement in matlab?? Could anyone please help?
