how to take Z transform of Exp term when Exp is Positive
For term like exp(-1.5 s) x 3/(s^2+4s+3) We can take the Ztransform or discrete form by this code clc Td=1.5; T=1; num=[0 0 3]; den=[1 4 3]; Gs=tf(num,den,'InputDelay',Td) Gz=c2d(Gs,T) [numz,denz]=tfdata(Gz); [A,B,C,D]=tf2ss(numz{1},denz{1}) But when i am having exp(1.5 s) x 3/(s^2+4s+3) (( negativ... 14 Jul 2010 12:04

Q: mnrfit contains slow code, but also commented-out line saying"Do these computations but more efficiently"
On 7/13/2010 5:54 PM, Raj wrote: It would certainly be nice to have this code run faster, and it appears to already contain more efficient alternative lines, except that they were put in but then commented out. Raj, you have it the wrong way around. The commented out code is in there simply to make the l... 14 Jul 2010 09:50

Struct size (bytes) strange behavior
I've been playing with us's vsize when I noticed this strange (?) behaviour in the example input: clear v v(1).a{1}=sparse(magic(3)+2i*magic(3)); v(2).a{2}={struct('FA',{'a','bb'},'FB',{magic(5),{}})}; v(2).b{2}=@(x) sind(x); % Size in bytes of v is: 1998 bytes v.a; v.b; % now is: 2012 bytes Can somebod... 14 Jul 2010 09:51

set the interpreter property to ‘none’
To keep the underscores in titles, labels and legends, I always need to add 'interpreter','none' to the command; Is there a way to avoid this and to set this as a default ? ... 14 Jul 2010 09:50

Exponential of a matrix indexed by a parameter
I have a matrix which is indexed by a parameter, something like: 2-x 3 4 1+x where x is a vector; so there is one matrix corresponding to each value of x. I want to take the matrix exponential of this. Is there a way to do it without using a "for" loop over all the values of x? Thanks, Mauro ... 14 Jul 2010 09:51
