fresnelMiss
Auxiliary function to deal with the missing transmitter-receiver links in Institute Fresnel's data set.
Contents
Syntax
fresnelMiss(A,FmeasDeltaFresnel)
Description
A = fresnelMiss(A,FmeasDeltaFresnel) identifies the missing transmitter-receiver links in Institute Fresnel's data set, that are given as NaN in FmeasDeltaFresnel, and transfers the missing links to A by set the corresponding entries to zero.
Input Arguments
- A : Matrix.
- FmeasDeltaFresnel : Matrix with Institute Fresnel's data.
Output Arguments
- A : Matrix as input matrix A with missing links set to zero.
More About
This is fuxiliary function is needed in the routines fresnelSynthPaper and fresnelSynthNuMaxVarPublic (as well as their intern predecessors fresnelSynth and frenselSynthNuMaxVar).
Note that Institute Fresnel's data set contains missing links for metrological reasons.

Code
function A = fresnelMiss(A,FmeasDeltaFresnel)
% miss: missing values (NaN in FmeasDeltaFresnel) are set to 0. % In IPscatt is FmeasDeltaFresnel available as seti.FmeasDelta.
Define a Mask (unsused)
% Introducing MM (missing mask) (this could be also used in loadData.m). % Missing data in Institute Fresnel's data set is marked with 0 (otherwise 1). MM = ones(size(FmeasDeltaFresnel)); MM(isnan(FmeasDeltaFresnel)) = 0; % 0: entry is missing in FmeasDeltaFresnel % 1: entry is available in FmeasDeltaFresnel % MM.*A does not work, if A contains NaN entries because 0*NaN = NaN. % Otherwise it would work % Maybe use it in case of synthetic data stored in A.
Identify NaN Entries
% loadData: in a workaround NaN values were set to 0 % (until missing values are otherwise taken into account). % So, set values in A to zero if they are not a number in FmeasDeltaFresnel. A(isnan(FmeasDeltaFresnel)) = 0; % This is also used in loadData.m.
Transfer Entries with 0
A(FmeasDeltaFresnel==0) = 0;
