For Loop No Idea!

So I'm not used to how you write programming code in Matlab, or really any language to be honest, so could someone tell me how to make this for loop work
for start = 1:VgStep:endPoint-VgStep
for step = VgStep:VgStep:endPoint
x1 = x(start:step);
y1 = y(start:step);
end
end
I think you can probably get the general idea of what I would like it to do..

could i use some kind of return command?

return will likely not help.
"break" might possibly help, perhaps.

Hello people kind enough to help.
I have got myself stuck again.
Apparently Matlab does not like this either
for i = 1:VgStep
for start = 1:VgStep:endPoint-VgStep
for step = VgStep:VgStep:endPoint
XX(i) = x(start:step);
YY(i) = y(start:step);
end
end
end
pops up with this error
In an assignment A(I) = B, the number of elements in B and I must be
the same.

x y Vg
0 8908 0
-1 908 0
-2 7897 0
0 8908 -1
-1 8908 -1
-2 789789 -1
0 8908 -2
-1 784732 -2
-2 89034 -2
That is more like what the data looks like sorry
and this is the rest of the code
x = A.data(:,1);
y = abs(A.data(:,2));
Vg = A.data(:,3);
minx = min(x);
MaxX = (-minx)+1;
VgMin = min(Vg);
VgStep = (-VgMin/1)+1;
endPoint = (VgStep*MaxX);

sorry just realised I was using the wrong brackets, should have been
for i = 1:VgStep
for start = 1:VgStep:endPoint-VgStep
for step = VgStep:VgStep:endPoint
XX{i} = x(start:step);
YY{i} = y(start:step);
end
end
end
