StdDevOfLayersToMatrix


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

The method StdDevOfLayersToMatrix calculates the standard deviation 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 processed 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.

StdDevOfLayersToMatrix increments the global variable ProcStat in 100 steps and calls the feedback routine MathFeedBackProc in order to allow feedback to the user during time consuming calculations.

Example: The statement StdDevOfLayersToMatrix (SMat,2,4,2,7,2,2,0,0); calculates the standard deviation of all matrix elements in the columns 2..4 and rows 2..7 for layer 2 in all time slots and stores the result in matrix SMat.
