Building a Table Within a While Loop
显示 更早的评论
I am having trouble building a table within a while loop. Here is how I have the loop set up:
while mwater>0
(The program performs operations on many variables here)
printcounter=printcounter+1;
if printcounter==9
T=table(t,Pair,Temp,Fthrust,Fgravity,Fdrag,Fnet,mwater,mair,mtotal,arocket,vrocket,x);
printcounter==0;
end
end
The way I have it set up, the entire table is rewritten with each iteration of the loop. I need each iteration to add another row onto the table, does anyone know how I could do this?

Build up each of your columns, in whatever way works, in advance. Use a loop if you have to. Then just call table() once after all columns have been constructed.

As an example:
printcounter = 0;
mwater = 1;
loopCounter = 1;
while loopCounter<5
printcounter=printcounter+1;
if printcounter==9
printcounter=0;
end
t(loopCounter) = loopCounter * 2;
Pair(loopCounter) = loopCounter * 3;
Temp(loopCounter) = loopCounter * 4;
Fthrust(loopCounter) = loopCounter * 5;
Fgravity(loopCounter) = loopCounter * 6;
Fdrag(loopCounter) = loopCounter * 7;
Fnet(loopCounter) = loopCounter * 8;
mwater(loopCounter) = loopCounter * 9;
mair(loopCounter) = loopCounter * rand(1);
mtotal(loopCounter) = loopCounter * sind(90*rand(1));
arocket(loopCounter) = loopCounter * 10;
vrocket(loopCounter) = loopCounter * 11;
x(loopCounter) = rand
loopCounter = loopCounter + 1;
end
T=table(t',Pair',Temp',Fthrust',Fgravity',Fdrag',Fnet',mwater',mair',mtotal',arocket',vrocket',x')
The ' is to transpose the row vectors into columns. Adapt as you see fit.
