mlib_SignalLPCCovarianceInit_F32 - initialization for
covariance method of linear predictive codingSYNOPSIS

#include
mlib_status mlib_SignalLPCCovarianceInit_S16(void *state,
mlib_s32 length, mlib_s32 order);
mlib_status mlib_SignalLPCCovarianceInit_F32(void *state,
mlib_s32 length, mlib_s32 order);
DESCRIPTION
Each function initializes the internal state structure for covariance method of linear predictive coding (LPC).The init function performs internal state structure alloca-
tion and global initialization. Per LPC function call ini-
tialization is done in LPC function, so the same internal state structure can be reused for multiple LPC function calls.PARAMETERS
Each function takes the following arguments: state Pointer to the internal state structure. length The length of the input signal vector. order The order of the linear prediction filter.RETURN VALUES
Each function returns MLIB_SUCCESS if successful. Otherwise
it returns MLIB_FAILURE.
