pem compilation
I am attempting to compile the 'pem' function (System Identification toolbox) to run in a standalone executable. I am only interested in using it for "secondary" model usage - I am not looking to create models with this function. (Currently I am creating initial models using other methods and using the 'pem' function... 5 Aug 2010 16:53
Boxplot Y-Axis Change
This is kind of a picky question but I would really appreciate any help. I have a y-axis label on a boxplot of around -4 x 10^-4 to 1 x 10^-4 (that is exactly how it is displayed). It increases by increments of 0.0002. However, I want it to display the y-axis label of -0.0004 -0.0002 0.0000 0.0002 . . . Any hel... 5 Aug 2010 12:26
Rectangular QAM Modulator Error in RTW
Dear, I tried to build "ert_shrlib.tlc" of a simulink model which uses Rectangular QAM Modulator block, i configured it as Input Type : Bit Constellation ordering: Gray Normalization method: Average Power Average power, referenced to 1 ohm (watts) = 1 Phase offset (rad): 0 the input is col. matrix of 416x1 f... 5 Aug 2010 11:19
Differentiation of a dirac function
I want to find out the first derivative of Dirac delta function. I got the answer from the symbolic toolbox and then converted it into a function handle. syms x a = matlabFunction(diff(dirac(x-10))); Matlab returns a = @(x)dirac(x-10,1) The answer is fine. Then, let's say if you evaluate a(10), the err... 5 Aug 2010 15:46
How to generate points follow softcore process?
I am a newbie in point process. Now I need to generate variate random variable with pdf: p(X)=anfa*lamda^N*exp(-sum(nuy/abs(xi-xl))^(2/kappa)) In which X is a vector X=[x1, x2.....,xi,..,xN] xi belongs to [0,1]^2 (is a coordinate of one point in R^2) We have known lamda, nuy, kappa, N. How do I gen... 5 Aug 2010 11:19
Creating function from input argument
I'm creating a function that requires a mathematical function as an input argument(i.e. not a matlab function). I want to input f(x,y) and then the matlab function will calculate certain things relating to f(x,y). How can I make it so that f(x,y) is recognised as a function of x and y instead of a matrix? Cheers. ... 5 Aug 2010 13:32
