length

Return the length of a quantized FFT

Syntax

length(f)

Description

length(f) returns the value of the length property of quantized FFT f. The value of the length property must be a positive integer that is also a power of the radix of the quantized FFT (f.radix). The length of the FFT is the length of the data vector that the FFT operates on.

Examples

f = qfft;
length(f)

returns the default 16 for the length of the FFT.
