extract
Functions
-
int main(int argc, char *argv[])
extract [ option ] idxfile [ infile ]
-l int
length of vector \((1 \le M + 1)\)
-m int
order of vector \((0 \le M)\)
-i int
codebook index \((0 \le j)\)
infile str
double-type data sequence
stdout
double-type extracted data sequence
The command takes two input sequence:
\[ \begin{array}{cccc} \boldsymbol{x}(0), & \boldsymbol{x}(1), & \boldsymbol{x}(2), & \ldots, \end{array} \]and\[ \begin{array}{cccc} i(0), & i(1), & i(2), & \ldots, \end{array} \]where \(\boldsymbol{x}(t)\) is an \((M+1)\)-dimensional vector. If \(i(t)\) is the same as the given codebook index \(j\), this command outputs \(\boldsymbol{x}(t)\). An example of the output is\[ \begin{array}{cccc} \boldsymbol{x}(1), & \boldsymbol{x}(4), & \boldsymbol{x}(5), & \ldots \end{array} \]The below example extracts 10th order vectors indexed as 0 from
data.d.extract -l 10 -i 0 data.idx < data.d > data.ext
- Parameters:
argc – [in] Number of arguments.
