Ptp

Return the range of values of a matrix/vector or of the given matrix axis, equivalent to Max() - Min(). Ptp - Peak to peak.

double vector::Ptp();

double matrix::Ptp();

vector matrix::Ptp(
const int axis // axis
);

Parameters

axis

[in] Axis. 0 — horizontal axis, 1 — vertical axis.

Return Value

Vector with ranges of values (maximum - minimum) .

Example

   matrix matrix_a={{10,3,2},{1,8,12},{6,5,4},{7,11,9}};
   Print("matrix_a\n",matrix_a);

   vector cols_ptp=matrix_a.Ptp(0);
   vector rows_ptp=matrix_a.Ptp(1);
   double matrix_ptp=matrix_a.Ptp();

   Print("cols_ptp  ",cols_ptp);
   Print("rows_ptp  ",rows_ptp);
   Print("ptp value  ",matrix_ptp);

   /*
   matrix_a
   [[10,3,2]
    [1,8,12]
    [6,5,4]
    [7,11,9]]
   cols_ptp [9,8,10]
   rows_ptp [8,11,2,4]
   ptp value  11.0
