Number of operations
noperations(q)
noperations(q) is the number of quantization
operations during a call to quantize(q,...) for quantizer object q.
This value accumulates over successive calls to quantize. You reset the value of noperations to
zero by issuing the command resetlog(q).
Each time any data element is quantized, noperations is
incremented by one. The real and complex parts are counted separately.
For example, (complex * complex) counts four quantization
operations for products and two for sum, because(a+bi)*(c+di)
= (a*c - b*d) + (a*d + b*c). In contrast, (real*real) counts
one quantization operation.
In addition, the real and complex parts of the inputs are quantized
individually. As a result, for a complex input of length 204 elements, noperations counts
408 quantizations: 204 for the real part of the input and 204 for
the complex part.
If any inputs, states, or coefficients are complex-valued, they
are all expanded from real values to complex values, with a corresponding
increase in the number of quantization operations recorded by noperations.
In concrete terms, (real*real) requires fewer quantizations
than (real*complex) and (complex*complex).
Changing all the values to complex because one is complex, such as
the coefficient, makes the (real*real) into (real*complex),
raising noperations count.
