|See also: MeanOfLayersToMatrix, StdDevOfLayersToMatrix, MinMax, MaximumOfLayersToMatrix|
The method MinimumOfLayersToMatrix calculates the minimum 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.
The function MinimumOfLayersToMatrix is available in two overloaded versions: version  automatically switches to multiprocessing if more than one CPU core is available. This speeds up calculations by a factor which is roughly proportional to the number of available hardware codes (supported only for Delphi/C++Builder XE4 or higher). Version  allows you to control the number of cores to be used for the calculation by setting the parameter NThreads.
