STATUSCONRAS is approaching obsolescence. If you have available an interpolation package which can do a random to gridded interpolation equal to that built into the Conran_family, then we recommend that you grid your dataset and use the Conpack utility instead. Refer to the conpack and conpack_params man pages as well as the NCAR Graphics Contouring and Mapping Tutorial.
- Input, real array -- of dimension NDP containing the X coordinates of the data points.
- Input, real array -- of dimension NDP containing the Y coordinates of the data points.
- Input, real array -- of dimension NDP containing the data values at the points.
- Input, integer -- is the number of data points to be contoured. NDP must be 4 or larger.
- Input, real array -- workspace of dimension 15*NDP.
Input, integer array -- workspace which must be dimensioned at
The parameter NCP controls the number of data points to be used in the interpolation. Increasing NCP causes more of the surrounding data to influence the point of interpolation. In the case of linear interpolation NCP is always 4. In the case of C1 interpolation, NCP can vary from 2 to 25 with 4 as the default.
The interpolation option is selected using parameter ITP. See the conran_family_params man page for a description of all internal parameters.
Real work array of dimension at least
(RESOLUTION**2) where RESOLUTION is
40 by default.
Alternate resolutions are set using parameter SSZ. See the conran_family_params man page.
USAGEThe contours will be drawn as smoothed dashed or solid lines using splines under tension. There may be characters along the lines. Crowded contour lines may be thinned. Many other options are available through the use of internal parameters. See the conran_family_params man page.
Quick and standard-and-smooth versions of the Conran_family are also available through entries CONRAQ and CONRAN, respectively.
EXAMPLESUse the ncargex command to see the relevant example tconas.
ACCESSTo use CONRAS, load the NCAR Graphics libraries conras, dashsupr, ncarg, ncarg_gks, and ncarg_c, preferably in that order.
The conras and dashsupr libraries are not loaded as part of the normal NCAR Graphics installation. They can be loaded by the user directly, or loaded implicitly through the use of the -super option of the ncargf77 command.
- Command: "ncargf77 -super mycode.f"
