Is there a command of "not less than or equal to " to vectors?

Hi, want to know if there is a command can compare if two vectors a is not <=b? Now I use while sum(le(a,b))~=N while N is the size of vector. However it is very inconvenient.

Thanks.

all(a<=b)

Thanks, Azzi, it means if all entry of a is <= b and if all is true returns a 1.

[Azzi Abdelmalek]

Exact, I guess it's what you need.

[Azzi Abdelmalek]

the comparison is done: the first element of a with the first of b, and so on

[C Zeng]

Thanks, I wonder if there is a faster way. That is, if we've seen any not<= entry, return 0, otherwise continue.

[Azzi Abdelmalek]

Maybe

~any(a>b)

But I don't think it will be much faster

[Walter Roberson]

No there isn't.

If I recall correctly, someone did submit a MEX routine to do vector comparisons, but unfortunately I cannot seem to locate it at the moment.

[C Zeng]

Oh, OK, Walter. But theoretically, it can be faster.
