Hello, i have a .m-File with an For Loop Iteration. This .m-File calls another .m-File ( Main.m ) to solve some Variables ( for Example 'XXX' ) from the Iteration-Value PC
for PC=850:10:870
EG=1286
Main
save test.dat XXX
end
So the Program should take every new Iteration-Step into the Main.m and solve Things in it ( for Example Variable 'XXX' ) and then save it to a new .m-File ( for Example test.dat ). The Output should looks like this:
Column1(Iteration-Steps) Column2(Value of the Variable XXX form Main.m )
850 64874
860 65879
870 69766
I hope you Guys understand my Problem, big thx!

Buff = zeros(numel(850:10:870),2);
Ctr = 1;
for PC=850:10:870
EG=1286
Main
Buff(Ctr, 1) = PC;
Buff(Ctr, 2) = XXX;
Ctr = Ctr+1;
end
save test.dat Buff;

Thank You, it works but ive found now a much easier way:
data = [];
for PC = 850:10:870
step=PC
EG=1286
Main
data = [data; step, XXX];
end
save test.dat data
i have a new Question, how i can now build EG=1286:10:1306 in this For-Loop operation, so i have the PC=850:10:870 and the EG=1286:10:1306 in a Loop.
It should calculate every value of PC and EG in the Main.m
Thank you Guys!

Thanks for posting your solution.
In your code you have not pre-initialized the variable - data and its size is growing in the loop. This makes the code to run slow as size of data will increase in the loop.
And regarding your new question, how your output will look in this case ?

Thanks for the Information. My Output should like this:
Column1 Column2 Column3
(Iteration PC=850:10:870 ) (Iteration EG=1286:10:1306) (Variable XXX)
850 1286 ...
860 1286 ...
870 1286 ...
--- --- ---
850 1296 ...
860 1296 ...
870 1296 ...
--- --- ---
850 1306 ...
860 1306 ...
870 1306 ...
This would be fantastic if this could work :-D

Thanks again, it works fine. I have a last Question ;) Now i want make a 3D-plot Surface of this data/values. How i can load the values of the columns from test.dat into a plot and the next question is: Must i use the Interpolation-command to create this surface. How it should looks like
