optmm

Smooth multiplier matrix using a two dimensional convolution. The function optmm</comp> was especially implemented for the script application MulAc.

Usage

optmm(mflag, a, w)

mflag

selects the method used to modify the multiplier matrix; currently only the method mflag=0 is implemented

a

The multiplier matrix. Each row a[i] contains one linear filter spectrum to be applied to a signal.

w

The smoothing matrix, containg a two dimensional a smoothing function.

Description

1. nrow(w) = 2M+1 and nrow(a) >> M
2. ncol(w) = 2N+1 and ncol(w) = ncol(a)

The matrix w contains the weighting function, with the center w[M,N] and should be symetrical in both dimensions

(w[M-i,N-j]=w[M-i,N+j]=w[M+i,N-j]=w[M+i,N+j]; with: i=1..M, j=1..N

Result

The vector r with the length nrow(a), containing the smooth filter spectrum.
