df = SCALAR, Represents the interval between
successive elements of returned vector.
N = SCALAR, any numerical type, coerced to INTEGER
before processing. Number of elements in returned
RETURN: COLUMN VECTOR. N-point linear frequency array, starting at 0(zero), same type as input.
Creates a column vector of N elements, starting at 0(zero) and linearly progressing in steps of 'df'. Return type is same as that of 'df'. N must be >0 or 'novalue' is returned. Useful for creating frequency axis vectors, or vectors used in procedures.
N = 11;
df = 30d0;
f = freqaxis(df,N);
