Spot operator: opHadamard | Spot Home Page |
opHadamard Hadamard matrix. opHadamard(N) creates a Hadamard operator for vectors of length N, where N is a power of two. Multiplication is done using a fast routine. opHadamard(N,NORMALIZED) is the same as above, except that the columns are scaled to unit two-norm. By default, the NORMALIZED flag is set to FALSE.
