how to automatically create "smart" files names
Hi, I would like Matlab to save data in a file whose name would contains some of the simulations parameters For instance, let's say I run simulations at various temperaturesT and pressures P, Can MAtlab automatically save the data in files whose name would be T_ 20_P_1 ,T_ 40_P_1, T_ 60_P_1.... So far to sa... 19 May 2010 07:08

Sample Time & integration
Hi, I am new to simulink and I am facing the following pb: I am trying to model the displacement of a mass bouncing between soft shock stops after experiencing a strong and brief shock/acceleration.-quite similar to the "bouncing ball" demo available on the help except that the acceleration in a one time pulse ra... 19 May 2010 08:13

Inscribed triangle in delaunay trianglation mesh
Dear All I need your help in MATLAB for constructing a shape. First I need to draw the set of triangular mesh . Inside the each triangle of the mesh, I need to draw an inscribed triangle. The boundary of the inscribed triangle is placed at certain distance with that of the triangluar mesh triangle. I used the... 3 Jun 2010 00:13

Pdepe, problem by setting the faktor c (from [c,f,s]) as a function of radius
Hello people I am trying to create a programm that computes the heat and temperature distribution in a cylinder that gives out heat via conduction, with pdepe. The tricky thing is, that the cylinder consists of 4 layers of different heat capacities, densities and thermal conductivities. So I used a sum of 4 heavisid... 19 May 2010 03:54

Any reliabillity engineering geek?
Hi, if suppose I have 20 identical samples and the required test time for them without failure is 100 hours. Now if out of these 20, I take 10 samples and test them for a time of 50 hours instead of 100 and the next 10 for a time of 200 hours. Then in the end what would be my total reliability? Assume confidence l... 19 May 2010 11:33

Rotate 3D object to align with x-y plane
Hi, I have a set of points describing a 3D object, which has been rotated by some small angle (below 45 degrees) with respect to x,y and z axis. I want to rotate it back to align it with the x-y plane, but the problem is I don't know the angles, so I need to calculate/estimate them somehow. So the questions are: ... 21 May 2010 10:35
