Optimization of a discontinuous function
I am facing the following problem. Consider the following function test_func(x): if x <= 0 y = 0; elseif x <= 1 y = 10000*x^2; elseif x <= sqrt(3) y = 5005*(3 - x^2); else y = 0; end This function evalutes to 10000 at x=1 and 10010 at x=1+\epsilon (i.e., just above 1). If I maximize thi... 26 Jun 2010 18:29

Fitting Implicit Nonlinear Functions
Hello everyone, I need help fitting a physically-known equation with unknown parameters to measured experimental data. The equation represents the I-V behavior of an ideal photovoltaic device (solar cell) and is as follows: I = A - B((e^CV)*(e^CGI) - 1) - DV - DGI where I is the current, V is the voltage and A... 20 Jul 2010 09:09

Function eval - Matlab 7.0 x Matlab 2010a
Hello, i'm a braziliam master's degree student in applied mathematics. I found different results working with the eval function in versions 7.0 and 7.10 of Matlab, could you explain these differences? I managed to circumvent the problem with small changes in my algorithm, but I wonder what changed. I thank you for yo... 23 Jun 2010 13:57

custom colormap problems
Hello, I'm writing a Matlab driver for a 3D LIDAR, which spits out images as requested. I'm trying to plot images, with a custom colormap. Each pixel is a single, and ranges from 0 to 200, or is -1 if "too close", or -2 for "too distant". I've tried creating a colormap as follows: colormap([0,0,0; 1,1,1; hs... 23 Jun 2010 10:36
