Personal Profile:

I'm a fluid dynamicist, currently finishing off my PhD at Cambridge University Engineering Department, UK. My specialist subject is turbulent structures in Boundary layers.

I do part time consultancy work covering tidal stream turbine design, general marine propeller/turbine design, experimental techniques (Particle Image Velocimetry and related) and design optimisation. I like to use MATLAB for most of my work!
Please feel free to contact me if you'd be interested in corresponding, or require a consultant for tasks similar to the above.

In my spare time, I walk, sail, go climbing, paint with watercolours (abstract and landscapes) and play electric guitar. At least, I would do all those things, if I wasn't using Matlab most of the time...

Professional Interests:

Fluid dynamics, Tidal Turbines, Marine Engineering, Propeller / Turbine Design, Design Optimisation

07 Dec 2009	Matlab Icon for Linux (with Transparency) A nice icon to use as Matlab start button in Linux. Author: Georg Stillfried	About time someone did it. Last install, I had to make one myself... now you've saved me the trouble :) Thanks!
26 Nov 2009	mpiv PIV method in MATLAB Author: Nobuhito Mori	DACE kriging toolbox can be found here: http://www2.imm.dtu.dk/~hbn/dace/
18 Nov 2009	Attractor Quadratic attractor,Clifford attractor,Peter De Jong generated using histogram method. Author: Ankur Pawar	I'll admit, this is cool looking (hence 2 stars), but to be honest, I don't feel it's satisfactory on other counts. A good file exchange submission is likely to meet several (not necessarily all) of the following criteria: - be a function which can be easily adapted for other purposes. - be a function which can be used 'out-of-the-box' for some useful purpose. - be well commented, including a description of the algorithm used, inputs and outputs, example usage, and comments interleaved with the code so the reader knows what's going on. - demonstrate a principle or programming technique - be well programmed (e.g. avoid the use of nested for-loops, use as-simple-as-possible programmatic structure etc). This submission meets none of those criteria, although I'd encourage the author to comment it more carefully, as I feel that the strange attractor is a tool which is poorly understood. Clearly the author has a good grasp of their application, and if communicated well, this could be very useful for the matlab community.
07 Nov 2009	find_components finds the connected components of an image Author: Tim Davis	Thanks Tim! This is very popular in the current ML contest (flooding a matrix with colour, Fall 2009).
11 Aug 2009	Polyfitn N-d polynomial regression model Author: John D'Errico	Fit for it's purpose ;) Thanks John, I had to chop and modify polyvaln for my application, but it was really good to have a way of generating the polynomial coefficients for a given n and order.

Author: Thomas Clark	Giaccari, Luigi	That'is it Ifound Mister clark there is nothing wrong in my pc, maybe you should turn the profile off when you run a new test try this.

05 Oct 2007	OceanMap Manually enter matrix elements in a GUI, then save to a *.MAT file. Author: Thomas Clark	Clark, Tom	Michele, ActiveX objects do not (usually) have a visibility property. Nor can they be embedded in an uipanel (which of course may be hidden along with it's contents). The only way to hide activeX objects (that I know of) is to move them: >move(handle,[x y wdth ht]); check out the help on move for more info. Don't forget to save the original position so you can move it back! --- Kind Regards Tom
26 Jul 2007	OceanMap Manually enter matrix elements in a GUI, then save to a *.MAT file. Author: Thomas Clark	Micheli, Michele	Thank you! just a question: is it possible to Hide/unHide the FlexGrid control?
09 Jul 2007	OceanMap Manually enter matrix elements in a GUI, then save to a *.MAT file. Author: Thomas Clark	Perlovskiy, Eugene	Thank's for good example. However, I don't know how use the ColWidth property of flexArray. I want to exchange a column width in flexArray. Can you help me?
