getX

TBi getX(int i)

Get the x[i] object, after the eqn is solved.

Parameters:

i - the element row number

Returns:

the x[i] element

setA

void setA(TAij x,
          int i,
          int j)

Set the aij object.

Parameters:

x - the aij object

i - the element row number

j - the element column number

getA

TAij getA(int i,
          int j)

Get the aij object.

Parameters:

i - the element row number

j - the element column number

Returns:

setBi

void setBi(TBi bi,
           int i)

Set b[i] object, before solving the eqn.

Parameters:

bi - the bi element

i - row number

setBVector

void setBVector(TBi[] bAry)
