A finite (µ, S)-frame variety consists of the real or complex matrices F = [f 1 · · · f N ] with frame operator F F * = S, and which also satisfyies f i = µ i for all i = 1,. .. , N. Here, S is a fixed Hermitian positive definite matrix and µ = [µ 1 · · · µ N ] is a fixed list of lengths. These spaces generalize the well-known spaces of finite unit-norm(More)
