I have a large matrix samples, I want to make another matrix sampleProb which is the same size, but modified as below:
%samples is a 1000*1000 matrix, M = 1000
for i = 1:size(samples, 2)
for j = 1:M
for k = 1:M
if (k ~= j)
sampleProb(j, i) = sampleProb(j, i) + normcdf(sample...

Here is the code for an A* search that I tried to write to solve a simple maze. However, it seems to be bugged in some form, as it expands 65,000 nodes for the following maze, when it should expand ~15,000 using a null heuristic:

I am interested in splitting any list into consecutive subsets based on a k-value. For example, [1,2,3,4,5] splits into [[1,2],[2,3],[3,4],[4,5]] when k=2. If k is bigger than the entire list, then an empty list will be returned.
