Example: Calculation of L1 Distance between points x = (3,4) and y = (2,3).

 

Function call: polynom_abs(matrix_1).

 

matrix_1:

 

 

The matrix_1 is in file matrix_1.txt in PSG Matrix format (see, PSG Matrix in General (Text) Format).

L1 Distance is calculated at point_1:

 

 

The point point_1 is in file point_1.txt (see, PSG Point).

 

To calculate L1 Distance at point_1 run problem in file problem_L1_Distance.txt (see, Calculate Problem):

 

calculate          

point: point_1      

value:              

 polynom_abs(matrix_1)

 

Value of polynom_abs(matrix_1) at point_1 equals 5
