Need to know how to trap int 21h function 09h using watcom or inline assembly
I am writing a application in which i want to convert the
textmode(03h=80x25x16) screen into graphics mode(12h=640x480x16). But
while doing this i want to read the textmode buffer from memory
address 0xb8000( i m using causeway as a extender). This application
is sucessfull to run in windows 98 dos session. But it doesn't works
on pure dos versions.so now i want to trap the specific interrupt
which writes the buffer to memmory.But i m not getting how to do it.i
know that in 21h function 09h does this. can any one give me some
hints or any code to know how to trap int 21h function 09h usi...visual c++ inline assembly migration to gcc inline assembly
Sorry for bad english you may encounter below.
I have some windows visual c++ inline assembly functions to migrate to
linux gcc inline assembly. The goal of these functions is to handle big
numbers used in RSA encyption/decryption systems.
I am not very familiar with gcc inline assembly. I spent two days on
migrating ln_copy(DWORD *p, DWORD *q)(copy the value of bignum q to p)
and ln_zero(DWORD *p) (set the value of bignum p to zero). I got really
frustrated. Now I have some more difficult functions which I just don't
know how to migrate.

I'm looking forward to a 3D plot function which would allow to display

with surf() but facets are drawn... As far as hist3d() is concerned, we

...How to plot a curve point by point?
Anyone has the idea about how to show a curve point by point? I use
plot(x,y), but all the point of the curve show up at the same time,
are there anyway i can control this procedure? thanks!

several possible approaches:

x=1:5; y = rand(size(x)) ;
1) create different line objects

I found out that Proc Gcontour can produce the contour
plot of Z=f(x,y). Normally, the contour plot is
superimposed on the plot of points of Y vs X. Can you
tell me how to create these two plots at the same
proc gcontour data=a;

...plotting points in 3d plot??
how to plot just points in 3d plot if i have three vectors of big
size (1500 x 1).
I dont want matlab to draw joining lines from these points...i just
want to see points in 3d plane...possible??
I think the command is:

I'm having a little problem to connect one point to several points.
I have a point : 1*2 matrix (A) and a 23*2 matrix (B). And I would like to link every points of the 23*2 matrix to my single point (1*2 matrix).. I tried several ways:
plot(A,B) .. doesn't work
plot(B,A) .. doesn't work
plot([A(1),B(1:end)],[A(2),B(2:end)]) .. doesn't work
plot([A(1,1),B(1:end,1)],[A(1,2),B(1:end,2)]) .. doesn't work
please, need help!!!

First, please excuse my bad english ...
I've done a experiment on the resistance of a material, and I would try to
trace (plot ?) my results on a curve, I've 12 points and I've done the
experiment twice, how can I plot this ?
J'ai fait un test pour evaleur la resistance d'un materiau et je voudrais

force en N, comment puis-je realiser cela ?
Mon pote qui travaille avec moi, utilise Mathlab, mais moi je suis sou...plot derivative; plot with points
I have two different queries on Gnuplot features:
(1) Is it possible to plot derivative of a data file? In other words,
if I have a data file that gives y-data as a function of x-data, can I
plot dy/dx in Gnuplot from the data file?
(2) I have a data file with many data points. I plot it 'with points'
option. The problem is that where the curve is flat (horizontal), the
points are too much dense, giving a thick-line like look, and where
the curve is steep, the points look rarer and the plot is ok. If I use
the 'every' option, say 'every 2', then the p...
