if then for non scalars and less equal comparison

Question

How would you implement:

if(m <= 0.1)
...
end

if m is not a scalar. I tried something along those lines:

array = ones(length(m), 1)  .* 0.1;
if(m <= array)
...
end

without success.

You likely want

if all(m <= 0.1)

but maybe

if any(m <= 0.1)

It's even one of the examples for the all function.

if (m <= 0.1)

should work just fine also.

+1: You could also use `mode` to check for the majority of values. – Eitan T Jul 01 '13 at 13:58
Note that `if (m <= 0.1)` is equivalent to `if all(m <= 0.1)` – Dennis Jaheruddin Jul 11 '13 at 13:44
