This function provides comparison operation improvement for floating point numbers.
Singleton expansion, multidimensional arrays supported.
example:
>> A = [ 1, 1, 1, 100, 1, 4];
>> B = [ 1, 1.2, 1.01, 101, 4, 1];
>> A<B
ans = 0 1 1 1 1 0
>> numcmp(A,B,1,1,@lt)
ans = 0 1 0 0 1 0

Version Published Release Notes
1.2.0.0

.
1.1.0.0

inf/nan errors solved. Please note that with numcmp infinities are not equal. inf == inf returns 1, while numcmp(inf,inf) returns 0. This is actually closer to reality:)
function rewritten, relative tolerance introduced.
bugs left to solve: eliminate errors when infs/nans are used.
1.0.0.0

Note, this function uses only absolute precision.
