UWSGXB/UWSGYB

DCL:GRPH2:UWPACK: Grid-Point Information Handling Routines: Explanation of Subroutines

11.2.2 UWSGXB/UWSGYB

1.

Function

Sets the grid point coordinates of the gird point array using the minimum and maximum values and the number of grid points.

2.

Call

CALL UWSGXB(UXMIN,UXMAX,NX)
CALL UWSGYB(UYMIN,UYMAX,NY)

3.

Explanation of Parameters

UXMIN, UXMAX (R) The minimum and maximum values of the X coordinate in UC.

UYMIN, UYMAX (R) The minimum and maximum values of the Y coordinate in UC.

NX (I) The number of grid points in the X direction. The grid point coordinates are set to divide the length equally between UXMIN and UXMAX into NX-1sections.

NY (I) The number of grid points in the Y direction. The grid point coordinates are set to divide the length equally between UYMIN and UYMAX into NY-1sections.

Notes

(a): When this subroutine is called, the value inquired by UWQGXZ/UWQGYZ becomes .TRUE..
(b): Unlike UWSGXA/UWSGYA, a work array is not used, so there are no limits for NX and NY. However, NX and NY must be larger than 2.
(c): The current minimum and maximum values and the number of grid points for the grid- point coordinates can be inquired with
CALL UWQGXB(UXMIN,UXMAX,NX)
CALL UWQGYB(UYMIN,UYMAX,NY).

`UXMIN`, `UXMAX`	`(R)`	The minimum and maximum values of the X coordinate in UC.
`UYMIN`, `UYMAX`	`(R)`	The minimum and maximum values of the Y coordinate in UC.
`NX`	`(I)`	The number of grid points in the X direction. The grid point coordinates are set to divide the length equally between `UXMIN` and `UXMAX` into `NX`-1sections.
`NY`	`(I)`	The number of grid points in the Y direction. The grid point coordinates are set to divide the length equally between `UYMIN` and `UYMAX` into `NY`-1sections.
