if statement - Simple code on Octave -

in case u vector of random numbers

 i=u     if (i<1)       i=i+1     endif   endfor

in end gives me vector i=u

if trying count number of elements less 1 then:

sum(u < 1)

or if wanted use loop need separate variable total:

count = 0 = u     if < 1         count = count+1;     end end
