I was hoping that some more experienced programmers could help me make my implementation of Dijkstra's algorithm more efficient. So far, I think that the most susceptible part is how I am looping through everything in X and everything in graph[v]. My graph is formatted as g = {1:{1:2}, 2:{2:3,...

The output is a (rows * columns) x 3 array of points. I've gotten the function to work perfectly, but it's way too slow! (takes like 2 seco...

I've recently started learning about lenses and for practice, I wrote a function that finds all paths from the root to a leaf of a tree for which the total of the nodes' weights is equal to a given value. My first version works on binary trees and is my first attempt at wrapping my head around l...

I wrote the following code to do some calculations. y1 = 0; for k = 1:L-1 for i = 0:N total1 = i*log(x) + 2*(n-m-i+k)*log(sig); for j = 0:N total2 = j*log(y) + 2*(n-m-j+k)*log(sig); for p = 0:100 total3 = 0; for q = 0:10...
