RandomFillMatrix

Declaration:

RandomFillMatrix (var Mat: TDouble2DArray; Mode: integer; Mean, Range: double): integer;

Fills the two-dimensional dynamic array Mat with random numbers whose properties are controlled by the parameters Mode, Mean and Range. The Mode parameter controls whether uniformly distributed random numbers are generated (Mode = 0) or normally distributed random numbers (Mode = 1). Depending on the type of distribution the other parameters have different meanings: Distribution Uniform (Mode=0) Normal (Mode=1) Mean median of the distribution mean of the distribution Range range of the distribution standard deviation

Example:

The statement RandomFillMatrix (MyMat,0,100,20); fills the matrix MyMat with uniformly distributed random numbers in the range between 90 and 110 (= Median +/- Range/2
