RATPOW Raise to rational power.
RATPOW(X,A,B) raises each element of array X to the power of its
corresponding element in array A./B, where both A and B must be
integers. Elements of B corresponding to negative elements of X must
be odd.
RATPOW(X,R) for real R, is same as RATPOW(X,A,B) where [A,B] = RAT(R).
Input arguments must be floating point arrays of reals.
See also radical,realpow.
Example:
>> x = [-1 -64; 81 32]; a = [1 1;2 2]; b = [3 3;4 5];
>> ratpow(x,a./b)
ans =
-1 -4
9 4
-----------------------------------------------------------------------
>> x.^(a./b)
ans =
0.5000 + 0.8660i 2.0000 + 3.4641i
9.0000 4.0000
>> realpow(x,a./b)
??? Error using ==> realpow
Realpow produces complex result.
