File Information
Description

'mpiv ', PIV toolbox in MATLAB, is a program made for the beginner of PIV (Particle Image Velocimetry) method. The main reason why I made this program was educational purpose for undergraduate and graduate student. The code is simple and may easy understand.

Since fall 2002, several algorithms has been added and mpiv has sufficient accuracy and options at present.
Required Products Image Acquisition Toolbox
MATLAB release MATLAB 6.5 (R13)
Other requirements DACE (A Matlab Kriging Toolbox) is required for advanced interpolations. Please down load it from http://www2.imm.dtu.dk/~hbn/dace/

This is good to understand PIV on MATLAB
15 Jan 2003 C.S kim

it's very useful for me

A good implementation of PIV in Matlab with excellent accompanying documentation.
21 Apr 2004 Anthony H

Excellent but it will be more helpful if the accompanying user manual can cover abit more information, especially for each function called during the tracking process.

Thanks Mr. Mori.

I had a problem getting th example data to work. The error was -->
??? Undefined function or variable 'dacefit'.

Error in ==> C:\MATLAB\work\mpiv_toolbox\vector_interp_kriging.m
On line 87 ==> [dmodel,perf] = dacefit( S, Y, @regpoly2, @corrgauss, theta );

the subpixel find function is incorrect. the x and y direction are interchanged.

Not advanced, but that's not the point - for someone learning PIV this is straightforward, flexible and extremely well documented.

Top marks, and thankyou for the time and effort which has clearly gone into this submission

:)

I have had the same problem as Glen Lichtwark - I receive the following error message: Undefined function or variable 'dacefit.' I'd appreciate it if someone could help with this.

If anyone else is having the same problem, you need to download the DACE kriging toolbox. Excellent program - many thanks.
