assigning multiple elements of a struct array
I have a 200x200 struct array S with multiple fields. One of the fields, S.pops contains a 10x2 array that tracks the population (in column 2) of the types with numerical IDs (column 1) at a particular site on the grid. For example it could be [1,10; 2,0; 5,1;...] and so on. Say I need to increment the population of... 25 Jul 2010 22:43

SimEvents randomising generator block seed in an model executable
Hi, I have a SimEvents model which is to be compiled to .exe, using the Real-Time Workshop (RTW) tool, that is to be used for Monte-Carlo simulations. I cannot work out how to make the seeds of the Event-Based Random Number Generators change at each execution of the compiled model. What I did is to set the see... 26 Jul 2010 09:25

Hello, I was wondering if there was a way to connect to an existing matlab engine session from a C program in Unix. I know that you can do it in windows using the Automation argument, but I haven't had any luck finding i... 25 Jul 2010 22:43

problem optimization with fmincon
Hi! I am working on simulations of a computing permit trading system. To do that, I am solving an minimization problem (objective function=addition of convex functions) under linear inequalities constraints. The unknowns stand for a (300,1) matrix at least for a beginning. I am using fmincon of the optimization toolbo... 28 Jul 2010 14:03

problem of index with system of ode
Hi I am a new new user of Matlab and have a system of non linear ODE but I am having a problem on the index. I have four variables T1,T2,T3,T4(T is the temperature) depending on time and varying with j. I would like to solve the system using ode45 and need your help on how I have to use the index with a loop to solve ... 28 Jul 2010 06:21

help with graphics/colormap/pcolor or whatever
Hello, I have a question that I am hoping someone here can help me with. I have a 82*100 matrix and for each row, I want to specify a certain range of values (3 different ranges) a specific color AND these ranges change for each row. For example, say anything in (1,:) is between -400: -100 I want it to be blue, and ... 25 Jul 2010 19:27
