When working with complex number computations some result, (a j. b) may satisfy
the equation (a=a+b) within tolerance. In that case it is reasonable to write
(b=0), even if the imaginary part b is not exactly equal to zero.
I wrote program f0 such that
f0 0.210224j2.92605e_98 _7.31512e_99j0.210224
0.210224 0j0.210224
like this
f1=.j./&(*(1,:-.&({. = +/)))&(|:&:+.)
f2=.f1&.:(*&0j1)
f0=.f1&f2
Why not include such functionality into the J system?
Thanks.
Bo.
