Matlab Diaries and Data Help with matlab and octave
Matlab/octave scripts or diaries for demos seen in class, or data/ scripts (for HWs):

• Apr22, Apr24 and Apr29 Diary of demos shown on Apr. 22, 24, and 29. Here are the related scripts
  • arn0.m
  • arnR.m
  • arnRD.m
  • CG.m
  • fom.m
  • gmres0.m
  • Lan.m
  • mark.m
  • mr.m
  • sorR.m
  • steep.m
  • subsit0.m
  • testArn.m
  • testProj3.m

• Apr10 Diary of demos shown on Apr. 10 You will need the following scripts.
  • testProj2.m Test driver for a few methods
  • fom.m full orthogonalization method
  • mr.m mr script
  • sorR.m sor
  • testMeshPart.m This is the driver I will use for testing your RSB1.m script in HW2. Make sure this works for your problem.

• testProj.m Test driver demonstrated on Apr. 8th. This requires the following scripts:
  • mr.m
  • rnsteep.m
  • sorR.m
  • steep.m

• Mar27 Diary of demos shown on Mar. 27 You will need the sorRelax.m script.

• Mar25 Diary of demos shown on Mar. 25 You will need the following data and script:
  • getCentroids.m
  • getClosestCtrs.m
  • jump.jpg Picture
  • makeRBFGraph.m make RBF weights
  • myKmeans.m my own (simple) kmeans.
  • scrop.m to crop figure
  • dsample.m to downsample
  • test2.m test with Kmeans
  • test.m test with Shi-Malik segmentation

• Scripts and data you will need for HW2:
  • get_mesh.m
  • mesh.xy Mesh vertices
  • mesh.edge Mesh edges
  • getMat.m script to build a subgraph
  • mygplot.m to plot domains with colors

• Mar13 Diary of demos shown on Mar. 13 You will need the following data and script:
  • hdisk2.m to generate a FEM mesh
  • mygplot.m to plot domains with colors

• Mar06 Diary of demos shown on Mar. 06 You will need the following data and script:
  • A8.8 matrix from page 8.8 of lecture notes
  • symb.m symbolic factorization .

• JKI1.m Script needed for Question~5 of HW1. You will also need fd3d.m for Question~5-b. The fd3d.m script calls sptridiag.m.

• Mar04 Diary of demos shown on Mar. 04 You will need the following data and scripts:
  • can_256.mat matrix from Harwell-Boeing collection
