Convert all elements of x from Hertz to ERB (equivalent rectangulare bandwidth) and vice versa.

Usage
hz2erb(x)
erb2hz(x)
x
a scalar, vector or matrix
Result
The result r has the same type as x and contains the converted elements of x.
hz2erb
ri,j = 16.7 * log10(1 + xi,j / 165.4)
xi,j is the frequency in Hz and must be greater than 0
erb2hz
ri,j = 165.4 * (10 ^ (0.06 * xi,j) - 1)
xi,j is the frequency in ERB and must be greater than 0
