Hello Alan, No problem about the e-mail format. One of my completion of course work proposals envolves a OpenCl-based filtering of ECG signal. I was having some problems loading the data in the device with C++, so I forgot that project. My final project now is only the circuit of a electrocardiography with a real-time plotting Qt gui. I saw that ktechlab was developing for Qt4. I think that its a pretty good idea
I am thinking, the algoritms probably work with state equations in matrix's and differential equations. So its a good start studying component models and matrix circuit solutions? A big improve it will be a simulation program that solves matrix problems with OpenCl or Cuda based algorithms. I don't know any Windows circuit simulation program, like NI Multisim, that do this kind of thing. Sorry for my english. 2016-08-27 11:39 GMT-03:00 Alan Grimes <alonz...@verizon.net>: > Mathias Scroccaro wrote: > > Hi , my name is Mathias , I'm a Brazilian university student.
