MeanOfLayersToMatrix

Unit: SDL_matrix
Class: TMat4D
Declaration: procedure MeanOfLayersToMatrix (DestMat: TMatrix; LowCol, HighCol, LowRow, HighRow, LowLayer, HighLayer, LowTimeSlot, HighTimeSlot: integer);

The method MeanOfLayersToMatrix calculates the mean of several two-dimensional submatrices and copies the result into the matrix DestMat. The range of each submatrix is specified by the parameters LowCol, HighCol, LowRow, and HighRow. The averaged submatrices are specified by the parameters LowLayer, HighLayer, LowTimeSlot, and HighTimeSlot.

As a shortcut, setting both the Low.... and High.... parameters to zero is equal to processing the entire range of available columns/rows/layers/time slots.

The destination matrix DestMat is automatically resized to accomodate to the number of processed data cells.

Example: The statement MeanOfLayersToMatrix (MeanMat,2,4,2,7,0,0,1,1); calculates the mean of all matrix elements in the columns 2..4 and rows 2..7 for all layers in time slot 1 and stores the result in matrix MeanMat.
