I have the problem with function abs as follow:

A1 =Quote:>A1

0.0072 + 0.0071i

-0.0079 - 0.0058i

0.0045 + 0.0037i

-0.0004 - 0.0039i

-0.0017 + 0.0047i

0.0020 - 0.0043i

-0.0015 + 0.0030i

0.0008 - 0.0003i

-0.0018 - 0.0016i

0.0017 + 0.0008i

??? Error using ==> absQuote:>abs(A1)

Function 'abs' is not defined for values of class 'single'.

How can i get the abs of this A1...

This must be a columm with ten element ??

Thanks...
