FRAMERED - Redundancy of a frame

Usage

red=framered(F);

Description

framered(F) computes the redundancy of a given frame F. If the redundancy is larger than 1 (one), the frame transform will produce more coefficients than it consumes. If the redundancy is exactly 1 (one), the frame is a basis.

Examples:

The following simple example shows how to obtain the redundancy of a Gabor frame:

F=frame('dgt','gauss',30,40);
framered(F)

The redundancy of a basis is always one:

F=frame('wmdct','gauss',40);
framered(F)
