Strange computations output
Please help me with the following. I perform simple calculations. Define a matrix A and substitute it into the equation:
A = [a11, a12; a21, a22]
syms x y
z = [x y];
S1 = (A(1, 1) - 1) * z(1) + A(1, 2) * z(2)
But the result is rather strange:
(122247597203675*x^2*y)/4503599627370496 - (553534918490399*x^3)/2251799813685248
Of course, if I divide these numbers I will get normal ones. But why MatLab does not do it by itself?

Does anybody know if it's possible to get an output from the simulink ode solvers that is comparable to the 'sol' structure returned by the command line solvers like ode45? I'm currently calling the simulink solvers by running the 'sim' command.
Specifically, I would like to be able to be able to interpolate (after the fact) into arbitrary time values using the correct interpolation for whatever solver was used - exactly the functionality provided for the ode45 suite by the method 'deval'.

Due to some historical reasons, we're using a mass flow controller to maintain pressure within an enclosure for leak testing (not much at all, 2"WC). Obviously in order for the PID to decrease the process value, it would need to set the flow controller to zero and turn on a 'vent' flow controller. I know this is really backwards, but what are your thoughts on properly implementing this with the standard PID vi? I've tuned the PID for one particular enclosure (which leaks, without using a vent controller) but am afraid of the ...Questions about some Ethereal output

That will be ok if you have a copy of the original copy.out/copy.in
scripts generated by copydb.
When dealing with character mode be mindful of losing floating point

I am using a 48-bit accumulator reference design from the XtremeDSP for

long clock to out time for the output of this block - 2.361 ns for the 10
speed grade in V4FX60. Looking at the datasheet this time is more in line
with the clock to out time from M register to P output. However, the M
register is not used in the design and the P-register is present... The time
analyzer designates this time as Tdspdck_opp while in the datasheet there
are Tdspcko_pp and Tdspcko_pm... The former is much lower than...parsing XML swapping nodes

Problem in using real time windows target is...
Just to check analog output, if a 0 constant is applied, output of
around 9 volt is obtained. This is for the very first simulation run.
Then when we make output channel 2( in analog output block), run the
simulation and change o/p channel back to 1 then run simulation again,
it gives 0 volt analog output which the the right value. After that it
always gives the right value. But if we do not change that channel to
2 and than back to 1, it keeps giving wrong analog output.

Among all the various wrinkles in interpretation and implementation

seem to agree that:

(pathname-directory "/tmp/foo/bar/") ==> (:ABSOLUTE "tmp" "foo" "bar")

element goes into the directory component of the pathname.
