[Scilab-users] log10 doesn't support hyperarrays

[Federico Miyara]

Dear all,

I've noticed that log10 doesn't support hyperarrays, while log (natural 
logrithm) does (even if the documantation in both cases says they are 
applicable to vectors and matrices:

a = rand(3,2,2);
b = log(a)
c = log10(a)
d = log(a)/log(10)

--> b = log(a)
  b  =

(:,:,1)

   -0.6847401  -0.0808957
   -1.051648   -0.0525378
   -0.9483546  -1.06847
(:,:,2)

   -0.9781346  -0.6944493
   -0.3091181  -1.3323448
   -1.3410298  -0.6436786

--> c = log10(a)
  c  =

   -0.2973788  -0.0351326
   -0.4567249  -0.0228169
   -0.4118652  -0.4640306

--> d = log(a)/log(10)
  d  =

(:,:,1)

   -0.2973788  -0.0351326
   -0.4567249  -0.0228169
   -0.4118652  -0.4640306
(:,:,2)

   -0.4247984  -0.3015955
   -0.1342483  -0.57863
   -0.5824019  -0.279546

As can be seen, log10 is yielding just the first page.

It's strange, since log10 can be easily obtained from log, but both 
functions are primitives

Regards,

Federico Miyara
