Detailed Description

Vector of real-valued data in double precision.

This file specifies the lvec_t buffer type, which is used in some places in aubio to store a vector of lsmp_t.

Note: the lvec_t data type is required in some algorithms such as IIR filters (see temporal/filter.h).

Definition in file lvec.h.
