[Isis-fish-users] recuperer une sous matrice en sommant sur une dimension

[Stephanie MAHEVAS]

Bonjour

je souhaite faire une calibration sur plusieurs annees. Je voudrais etre 
sure que j'utilise correctement sum.OverDim().
Est-ce que L = L.sumOverDim(0,12) permet d'avoir un cumul de L sur la 
dimension 0 de 0 à 11 puis de 12 à 23, ect...

je mets le script ci-dessous issu de Calibration.java écrit par Sigrid 
(je crois?).

merci
STeph

  MatrixND L2 = result.getMatrix(param_Population, 
ResultName.MATRIX_CATCH_WEIGHT_PER_STRATEGY_MET_PER_ZONE_POP);
/////*** If some strategies, metiers or areas must not be included in 
the cumulated catches see below else put "//" at the beginning of line 
297 and replace "L2" by "L" at line 289
/////*** the strategies or so to exclude must be at the begining or end 
of the list you enter in the parameters interface
/////*** fill the line  MatrixND L = L2.getSubMatrix(a,b,c).copy(); as 
follow :
/////*** a = 1 if you want to exclude strategies, 2 if metiers and 4 if 
areas
/////*** b = indice of the first object considered
/////*** c = number of object to keep after b, b included
  MatrixND L = L2.getSubMatrix(1,2,4).copy(); // for instance : keep 
strategies 2,3,4,5
// si tu veux toutes les strategies:
  // MatrixND  L = L2;
///*** if observations are cumulated over quarter a = 3, over year a = 
12, else put "//" at the beginning of the following line
// L = L.sumOverDim(0,a);
    L = L.sumOverDim(0,12);//sum over dates
    L = L.sumOverDim(1);// sum over strategies
    L = L.sumOverDim(2);// sum over metiers
    L = L.sumOverDim(4);// sum over zones
    L = L.reduce();
