Normality test Question Hi all, I just wonder if the normality tests in MATLAB can handle data in the format of a frequency distribution table (Variable X, Frequency N). Your advice is appreciated. Thanks. Kind Regards ... 10 Aug 2010 00:28
Mat-file program with %VAL construct Dear Friends, We are troubled by the fact that %VAL construct doesn't seem to work with Mat-file 'stand-alone' programs. Our compiler has been set to work perfectly if not %VAL construct was used. However, we were getting used to write programs with %VAL in our previous mex files as it passes the addresses thus avoi... 13 Aug 2010 13:34
What is the program of excel solver in MatlaB? I have a data in excel which i need to make an optimization analysis. . In excel, using the solver, it's easy. . I just choose a cell with a formula then pick the cells i need to change and add constraints then minimize.. but, in matlab i really dont have a clue. . I was able to import my data to matlab but i dont know... 11 Aug 2010 09:15
Coordinates arrays to plaid I've got some (r,t,z) triplets (derived from cart2pol) that are in arrays. If you look at (r,t) in polar space, say via plot(r,t), they are in a regular grid (to within roundoff error). However, they are not ordered in a regular way, so I can't do something like reshape. Since values are repeated, I also can't use m... 10 Aug 2010 01:33
different results between sessions I'm grasping at straws here. This situation is: The task has been to converted Matlab to CPP and validate before integrating into the system. I am runnning several (minimum of 5) Matlab session over a period of a weekend to produce validation data. Each session is calling a CPP routine from Matlab and when it return... 10 Aug 2010 10:13
estimate states of state space moddel using system identification toolbox After the state space model is trained use pem in system identification toolbox, how to estimate the states with the data. The predict function can only be used to get observed value. Thank for your help ... 9 Aug 2010 21:13
excel plot problem Hi guys, well I've manage to plot a set a a graphs in excel using matlab via the actxserver of course.......and I almost succeeded except There is a little bump in the road that I encountered. 2....I'm trying to change the gap width of data to 50 1....the alignment of the data on the x-axis has to be pointing up... 10 Aug 2010 09:05
Solving a linear overdetermined system with 8 unknowns I have a set of 10000 data points (x,y,z) with which the following system is created B*c = 0 B1 = z.^2+x.^2; B2= -2*z; B3 = y.^2; B4 = ones(length(x), 1); B5 = x.*z; B6 = y.*z; B7 = x.*y; where the unknown variables are c = [k1 k1*z0 k2 (k1*z0^2 - R) k3 k4 k5]' The system is solved with B... 10 Aug 2010 08:00
Two sets of time stamped data Hi there, I have two sets of data, one containing points with time stamps from sets X andY and a corresponding value of 0/1(relating to a particular aspect of animal behaviour) The second set contains only the points Y. The points Y determine particular states, ie s1 is given as a function of Y2-Y1 I need to determ... 9 Aug 2010 19:00
Annotation Problem Hi, I have the following data: P:= [1,1;2,2;3,2;3,3;4,4] I am using the following command: for i = 1:size(P,1)-1, figure1 = line(P(i:i+1, 1), P(i:i+1, 2),'LineWidth',2, 'LineStyle','-'); annotation(figure1,'arrow'P(i:i+1, 1), P(i:i+1, 2)); end and I am getting the following error: First argument ... 9 Aug 2010 19:00 |
