Understanding FFT output
...tputs because you are using a complex to complex FFT. Remember that you've converted your 32 samples into 64 values (or 32 complex values) by extending it with zero imaginary parts. This results in a symetric FFT output where the frequency result occurs twice. Once ready to use in the outputs 0 to N...
Standardize data columns in R
...the output of scale is Nx1 matrix so ideally we should add an as.vector to convert the matrix type back into a vector type. Thanks Julian!
EDIT 2 (2019): Quoting Duccio A.'s comment: For the latest dplyr (version 0.8) you need to change dplyr::funcs with list, like dat %>% mutate_each_(list(~sca...

...iterator();
// Zipping looses DISTINCT and SORTED characteristics
int characteristics = aSpliterator.characteristics() & bSpliterator.characteristics() &
~(Spliterator.DISTINCT | Spliterator.SORTED);

What is Mocking?
...objects. This is useful if the real
objects are impractical to incorporate into the unit test.
In short, mocking is creating objects that simulate the behavior of
