Hello everybody,
I do have a code, I cannot find the mistake. I get the error:
" if A(c-1,3)==0 then
!--error 21
ungültiger Index.
at line 11 of exec file called by :
exec('M:\CAD\Abteilungen\Praktikanten\Nikolaisen,
Frieder\Fahrdaten\Testprogramm\Archive\test2.sce', -1)"
My minimal example Code with random Matrix instead of the real used
one:
//example code
for c=1:10
A=rand(10:30)
dm=0
vor_starter=0
starter=0
//start of buggy code
if c>=2 then
if A(c-1,3)==0 then
if A(c,7)>0 then
beginnZ=c
vor_starter=1 /
end
end
//Endzeile festlegen
if vor_starter==1 then
if A(c-1,7)>0 then /
if A(c,7)<=0 then
endZ=c-1
starter=1
vor_starter=0
end
end
end
//Berechnung der Zugmasse
if starter==1 then
time3=datevec(A(beginnZ,1))
time4=datevec(A(endZ,1))
delta_t=etime(time3, time4)
delta_v=(A(endZ,3)-A(beginnZ,3)*3.6) // m/s
length_F=length(beginnZ:endZ)
mittel_F=sum(A(beginnz:endZ,6)/length_F)
dm= (delta_t/delta_v) / mittel_F
starter=0
end
end
if dm~=0 then
disp(dm)
end
// end of buggy code
end
The real Matrix Looks like These:
Zeit Distanz Geschwindigkeit 1 Drehzahl Getriebeausgangsleistung
[Watt] Zugkraft [N] Beschleunigung [m/s^2] Cv-Druck Richtung Lokbremse
