power

Fixed-point array power (.^)

Syntax

c = power(a,k)
c = a.^k

Description

c = power(a,k) and c = a.^k compute element-by-element power. The exponent k requires a positive, real-valued integer value.

The fixed-point output array c has the same local fimath as the input a. If a has no local fimath, the output c also has no local fimath. The array power operation is performed using default fimath settings.

Examples

Compute the power of a 2-dimensional array for exponent values 0, 1, 2, and 3.

x = fi([0 1 2; 3 4 5], 1, 32);

px0 = x.^0 
px1 = x.^1 
px2 = x.^2
px3 = x.^3
