.SH DESCRIPTION
.sp
.LP
The \fBmlib_SignalDTWScalarInit_F32()\fR function initializes the internal state structure for dynamic time warping (DTW) of scalar data.
.sp
.LP
The init function performs internal state structure allocation and global initialization. Per DTW function call initialization is done in DTW function, so the same internal state structure can be reused for multiple DTW function calls.
.SH PARAMETERS
.sp
.LP
The function takes the following arguments:
