Parameters

[in]	STI	Real*4 i grid coordinate of the point for which an interpolated value is desired.
[in]	STJ	Real*4 j grid coordinate of the point for which an interpolated value is desired.
[in]	FLD	Real*4 size(ii,jj) data field.
[in]	II	Integer*4 number of columns in 'fld'.
[in]	JJ	Integer*4 number of rows in 'fld'.
[in]	NCYCLK	Integer*4 code to specify if grid is cyclic or not: = 0 Non-cyclic in ii, non-cyclic in jj = 1 Cyclic in ii, non-cyclic in jj = 2 Cyclic in jj, non-cyclic in ii = 3 Cyclic in ii, cyclic in jj
[in]	LIN	Integer*4 code specifying interpolation method: = 1 Linear interpolation .NE.1 Quadratic interpolation
[out]	HI	Real*4 data field value at (sti,stj) obtained by interpolation.
