Syntax
C#

    public void LoadBasis(
    	int[] rowstat,
    	int[] colstat
    )

#### Parameters

rowstat Int32
  Integer array of length ROWS containing the basis status of the slack, surplus or artificial variable associated with each row. The status must be one of:
  - XPRS_BASISSTATUS_NONBASIC_LOWER (0): slack, surplus or artificial is non-basic at lower bound;
  - XPRS_BASISSTATUS_BASIC (1): slack, surplus or artificial is basic;
  - XPRS_BASISSTATUS_NONBASIC_UPPER (2): slack or surplus is non-basic at upper bound.
  - XPRS_BASISSTATUS_SUPERBASIC (3): slack or surplus is super-basic.
colstat Int32
  Integer array of length COLS containing the basis status of each of the columns in the constraint matrix. The status must be one of:
  - XPRS_BASISSTATUS_NONBASIC_LOWER (0): variable is non-basic at lower bound or superbasic at zero if the variable has no lower bound;
  - XPRS_BASISSTATUS_BASIC (1): variable is basic;
  - XPRS_BASISSTATUS_NONBASIC_UPPER (2): variable is at upper bound;
  - XPRS_BASISSTATUS_SUPERBASIC (3): variable is super-basic.
