Local documentation
April 6, 2005 FAQ No comments
Is there a place on my own machine where I could point my browser to see the program self-documentation?
Yes, point it to $RSFROOT/doc/index.html. The contents should be identical to those on the selfdoc page.

sfmath
April 1, 2005 Programs No comments
sfmath can now work with complex numbers. Try something like
sfmath n1=100 type=complex output=”exp(I*x1)” | sfgraph screenratio=1 | xtpen
You cannot, however, mix float and complex files in the input. Use sfdd, sfrtoc, sfreal, sfimag and sfcmplx to convert between real and complex types.
sfmath n1=100 output=x1 | sfrtoc | sfmath output=”exp(I*input)” | sfgraph screenratio=1 | xtpen

In pbi/modl/random, Jim Jennings creates an example of random correlated field with exponential covariance.
Figure size
March 28, 2005 FAQ No comments
How can I control the figure size or aspect ratio?
There are three basic parameters: screenratio, screenht, and sreenwd. If sreenwd is not provided, it is calculated as screenht/screenratio. The defaults are:
screenratio=0.75
screenht=10.24
For a finer control, you can use xinch= (horizontal size), yinch= (vertical size), xll=, xur=, yll=, yur= (x and y coordinates for lower-left and upper-right corners). If not provided, they are calculated from screenht and screenwd.
These parameters apply to sfcontour, sfgraph, sfgrey, sfplotrays, and sfwiggle.
Color schemes
March 28, 2005 FAQ 2 comments
What color schemes are available in sfgrey and sfgrey3?
The color scheme in sfgrey and sfgrey3 is selected by color= parameter. The default is color=I.
The picture shows different color schemes available.
Changing from uppercase to lowercase letters reverses the color scale:
Adding “C” to the colorscheme name highlights the clipped values:
These examples are taken from rsf/rsf/sfgrey.
Guide to RSF programs: sfdd

A section on sfdd has been added to RSF programs guide. Any further additions or corrections would be appreciated.
We probably need to add an option to sfdd to do byte-swapping without changing the data format: useful for transfering files in native form between big-endian and little-endian machines.
