How to split an array?
显示 更早的评论
Hi everyone,
May someone help me.
I have data in column and want to split this in two set by the condition of third point:
For example,
a=[1,4,6,9,13,17,20];
If we have 7 as a spliting number than the output is
[1,4,6]
and
[9,13,17,20]
I need generazlied function to compute this.

Use logical indexing‘:
a=[1,4,6,9,13,17,20];
b1 = a(a<7)
b2 = a(a>7)
producing:
b1 =
1 4 6
b2 =
9 13 17 20
EDIT —
A ‘generalized function’ version would be something like this:
vsplit = @(v,n) {v(v<n); v(v>n)};
b = vsplit(a,7)
b1 = b{1}
b2 = b{2}
The result is the same.

And might also want <= or >= in case 7 exactly is in there.

This could work:
if (all(a > c)) || (all(a < c))
return
end
I tested that as well as I could. I runs without error and (if I understand correctly what you want to do) produces the correct result.
