Sir,
Can you please tell me how to write the complex poles and zeros in the icd toolbox as when i start writing the poles and zeros using the imaginary form it shows error
please help
MIMO Channel capacit improvement employing coding technique
what is the easy code can implement my topic
I try to reproduce the following example:
g11=tf([1 1],[1 3 2]);
g12=tf([1 4],[1 1]);
g21=tf([1 7],[1 2 1]);
g22=tf([1 2],[1 5 6]);
G=[g11 g12 ; g21 g22];
[M,poles,zeros]=smform(G);
However I get the following error:
Subscripted assignment dimension mismatch.
Error in sym/privsubsasgn (line 1107)
L_tilde2 =
builtin('subsasgn',L_tilde,struct('type','()','subs',{varargin}),R_tilde);
Error in sym/subsasgn (line 944)
C = privsubsasgn(L,R,inds{:});
Error in smform (line 69)
d1(k)=lcm(factor(d(i)),factor(d(i-1)));
Any help will be highly appreciated.
The error @mohammadisaac hosseini raised should be fixed now.
hi
Error in smform (line 69)
d1(k)=lcm(factor(d(i)),factor(d(i-1)));
Where is the error?
- The problems related to the use of `simple` should have been resolved in the version that is currently on github.
- The issue that @hassan raised can be resolved in parts as described [here](https://github.com/OVivero/mimoToolbox/issues/2).
I have the following Errros :
I was trying with
[R,S]=rga(AS_u,BS_u,CS_u,DS_u,0)
AS BS CS DS are my systems Matrices
In sym/inv (line 22)
X = privUnaryOp(A, 'symobj::inv');
In ss2sym (line 37)
g=simple(c*inv(p*eye(n) - a)*b +d);
In rga (line 78)
g=ss2sym(a,b,c,d);
anybody can help ?
not working with Matlab 2015
@hassan
I think you need Maple for using this toolbox.
hi, I get the error msg
Undefined function 'maple' for input arguments of type 'sym'.
Error in smform (line 80)
S=maple('smith',P,p);
can you help?! please!
Its a great toolbox.
However, I am facing some errors in my Matlab 2014b.
And I am getting this even when I run the given example:
Warning: Function 'simple' will be removed in a future release. Use 'simplify' instead.
> In sym.simple at 41
In tf2sym at 54
In smform at 48
Error using symengine (line 58)
Array sizes must match.
Error in sym/privBinaryOp (line 835)
Csym = mupadmex(op,args{1}.s, args{2}.s, varargin{:});
Error in sym/lcm (line 27)
cSym = privBinaryOp(args{1}, args{2}, 'symobj::zip', 'lcm');
Error in smform (line 69)
d1(k)=lcm(factor(d(i)),factor(d(i-1)));
good
This is a useful and well-written toolbox! Thanks!
oh god !!
Certainly possible, but it will have to wait. I haven't upgraded my Matlab version at the moment (still on 2007b I think).
Would it be possible to incorporate the MuPad engine on this? I understand Matlab R2009+ do not use the maple engine (needed for smform). Thank you.
Thanks for sharing
THANKS!
hi
tanks for your kind consideration
good
The code is very well documented, and the author is extremely helpful and prompt in responding to any questions.
thanks to the author for distributing this helpful toolbox
hallo
Good for MIMO system analysis, particularly for calculation the zeros and poles
Excelent tool for continuos time systems. I hope there will be a 2.0 ver. with discrete time support.
Excellent
Very usefull
