## non-square root function? Hi, What is in scilab the inverse function of power, e.g. the non-square root? 2**2 = 4, so sqrt(4) = 2. But 2**3 = 8, so the 3rd-power root of 8 = 2. But what is the function in scilab? Thanks.

## RE: non-square root function? Uhm that is basics math problem and there is no special function for it (as far I know): sqrt(4) = 4^(1/2) = 2 3root(8) = 8^(1/3) = 2 4root(16) = 16^(1/4) = 2 Cheers -----Original Message----- From: news [mailto:[hidden email]] On Behalf Of Huub van Niekerk Sent: 14 January 2009 09:18 To: [hidden email] Subject: [scilab-Users] non-square root function?

But since the sqrt function is there as well... I'll use the ^ then. I understand but just like there are infinite powers there are infinite roots and to give them all separate functions is impossible. If you like to use a function (which sqrt actually is) for aesthetic reasons than why not write your own. -----Original Message----- From: news [mailto:[hidden email]] On Behalf Of Huub van Niekerk Sent: 14 January 2009 09:55 To: [hidden email] Subject: [scilab-Users] Re: non-square root function?
