PIVMat Toolbox

Version 1.30 20-Dec-2005 
F. Moisy 
 
This toolbox contains a set of functions to postprocess and analyse 
PIV fields from LaVision's Davis.  The LaVision's ReadIMX Loader Package 
is required (see the readme.txt file for installation instructions). 
 
Basic VEC/VC7 and SET handling 
  loadvec           - Load vector field(s) in Davis format 
  loadset           - Load set(s) of vector fields 
  loadpivtxt        - Load a Davis vector field exported in TXT mode 
  loadarrayvec      - Load a 2D array of vector fields 
  vec2mat           - Convert VEC/VC7 files into MAT-Files 
  showvec           - Display vector field(s) 
  showscal          - Display scalar field(s) 
  vec2scal          - Convert vector into scalar field(s) 
  batchvec          - Execute some functions for a series of files 
 
Field processing (both for vector and scalar fields): 
  filterf           - Spatial filter of a field 
  bwfilterf         - Spatial Butterworth filter of a field 
  averf             - Average of several fields 
  spaverf           - Spatial average over X and/or Y of a field 
  subaverf          - Substract the average of field 
  truncf            - Truncate a field 
  extractf          - Extract a rectangle from a field 
  rotatef           - Rotate a field about the center 
  shiftf            - Shift the axis of a field 
  operf             - Other operations on fields 
  addnoisef         - Add noise to a field 
 
Histograms & statistics 
  statf             - Mean, standard deviation and rms of a field. 
  histf             - Histogram of a field. 
  histvec_disp      - Display histograms from vector fields. 
  histscal_disp     - Display histograms from scalar fields. 
  statvec_disp      - Display statistics from vector fields. 
 
Advanced files handling (from Fileseries toolbox v1.01) 
  rdir              - Recursive list directory. 
  rdelete           - Delete files recursively. 
  rrmdir            - Delete directories recursively. 
  renamefile        - Rename a series of files. 
  renumberfile      - Re-number the indices of a series of files 
  getfilenum        - Get the index of a series of files. 
  expandstr         - Expand indexed strings. 
 
Miscellaneous 
  getsetname        - Get the name of the current set 
  getimxtime        - Extract PivDt and Frametime from READIMX data 
  randvec           - Random vector field. 
  vortex            - Vector field with a vortex.
