realpow (MATLAB Functions)

Array power for real-only output

Syntax

```
Z = realpow(X,Y)
```

Description

Z = realpow(X,Y) raises each element of array X to the power of its corresponding element in array Y. Arrays X and Y must be the same size. The range of realpow is the set of all real numbers, i.e., all elements of the output array Z must be real.

Examples

X = -2*ones(3,3)

X =
     -2     -2     -2
     -2     -2     -2
     -2     -2     -2

Y = pascal(3)

ans =
     1     1     1
     1     2     3
     1     3     6

realpow(X,Y)

ans =
    -2    -2    -2
    -2     4    -8
    -2    -8    64
