Dijkstra Shortest Path Algorithm Source Code with MATLAB Implementation

This source code is compatible with MATLAB 6.0 (R12) environment and implements Dijkstra's algorithm for computing shortest paths in graphs. Dijkstra's algorithm is a greedy algorithm that solves the single-source shortest path problem for graphs with non-negative edge weights. The core implementation maintains a priority queue (typically using MATLAB's min-heap operations) to efficiently select the next vertex with the smallest tentative distance. The algorithm works by iteratively expanding the shortest known path from the source node until reaching the target node. Key implementation features include: - Initialization of distance arrays with Inf values - Maintenance of visited/unvisited node sets - Path reconstruction using predecessor tracking - Weighted adjacency matrix representation This code provides practical insights into algorithm implementation details and MATLAB-specific programming techniques. The implementation demonstrates proper handling of edge cases and includes error checking for invalid inputs. If you encounter issues during usage, please refer to the code documentation or seek professional technical support for MATLAB-specific optimization suggestions.
