These codes are for the paper "Rank-One NMF-Based Initialization for NMF and Relative Error Bounds under a Geometric Assumption". The structure is as follows.

1. demo.m includes the example codes for a synthetic dataset and a real dataset;
2. The codes for main algorithms are included in the folder named “algorithms";
3. The codes in the folder named “plotFuncs" are only used for plotting the results;
4. The folders named “output" and “Figures" are used for saving the output and figures produced respectively;
5. The dataset files are provided in the folder named “dataset”;
6. The codes to produce results for synthetic experiments are included in the folder named “Synthetic";
7. The codes to produce results for real-dataset experiments are included in the folder named “realDataset";
