For loop inside structure
显示 更早的评论
I have a structure called (level3) and inside it some fields (e.g x0, vx). each field is an array with some values as shown in the screenshot.
I would like to go through these fields values and multply them as follows:
x(1,1)*vx(1,1)
x(2,1)*vx(2,1)
x(3,1)*vx(3,1)
.... and so on.
so I got at the end 10 arrays of results of x
I tried to do it like this but I just got one array with the last value.
fields = fieldnames(level3);
for k=1:10
x = [x0. * vx];
end
Thanks in advance

Those square brackets are superfluous. Get rid of them.
Note that your inner loop serves no purpose, because you do not use its loop index anywhere and none of its iterations depend on previous iterations, so the results of every of its iteration will get discarded except for the last one.

If I understand this correctly you're trying to capture the array of multiplications (x0 .* vx) for all of the different elements of the structure. I believe that all you're missing then is either an index on x, or to concatonate the results of x with the previous values.
fields = fieldnames(level3)
x = [];
for k = 1:10
x = [x;[x0.*vx]];
end
