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

13 Jan 2012 Sampling from a discrete distribution The function is to draw samples from an arbitrary discrete distribution. Author: Dahua Lin

Very useful, a good utility function which saves some though when implementing MC models.

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. Especially
before giving low and inappropriate rating.

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

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?
