Example: Function call: fxchg_neg(0.001,matrix_54).Parameter = 0.001 and matrix_54:

 

 

x1

x2

x3

x4

0.5

1

1.1

1

2.5

1

0.002

1

 

 

The matrix_54 is in file matrix_54.txt in PSG Matrix format (see, PSG Matrix in General (Text) Format).

Fixed Charge Negative is calculated at point_1:

 

component_name

value

x1

x2

x3

x4

-1

0

-1

 

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

 

To calculate fxchg_neg at point_1 run problem in file problem_fxchg_neg.txt (see, Calculate Problem):

 

calculate

Point: point_1

Value:

 fxchg_neg(0.001, matrix_54)

 

Value of fxchg_neg(0.001, matrix_54) at point_1 equals 0.502
