Dear folks,
calc R3-4 is now available here:
http://www.aps.anl.gov/bcda/synApps/calc/calc.html
Release 3-4
- acalcout record: new functions, better treatment of subranges:
- IXMAX: index of largest array element
- IXMIN: index of smallest array element
- IXZ: index of first zero crossing in array
- IXNZ: index of first nonzero array element
- FITQ, FITMQ: fit to quadratic and optionally return fit coefficients. (Replacements for deprecated FITPOLY, FITMPOLY.)
- CAT: concatenate array subranges, or an array subrange and a double.
- operators
^ and ** reimplemented to permit noninteger exponents.
- acalcout expressions now maintain array extents on the stack, so, for example, the _expression_
avg(aa[1,10]) really is an average of just aa[1,10] . Previously,
avg(aa[1,10]) actually performed sum(aa[1,10])/arraySize . Now it does
sum(aa[1,10])/10 .
- scalcout and transform records: operators
^ and ** reimplemented to permit noninteger exponents.
- use Perl's ExtUtils::Command to concatenate .dbd files, instead of local cat.pl. Left old stuff in place, for now, in case someone has a problem with the new method.
- Minor improvements in interp
- When an scalcout fails to fetch a string field, give an informative error message.
Release 3-3
- The transform record now supports expressions with user-specified variable names. For example, instead of the _expression_ "a-b/2", you could arrange to write "$center+$size/2". Variable names are specified using the CMTx fields. The sizes of calc fields
have been increased from 80 to 120 to better accommodate variable names. (See http://www.aps.anl.gov/bcda/synApps/calc/transformRecord.html#Expressions)
- Make it easier to add 10 more usercalcs by writing, e.g., userCalcouts10more.db
