How to split an array?

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.

hi , see this .. where to inset loops for generalzed calculation for each column

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.
