NAME
subandexpand.m
USAGE
is used as a template for secdec/subdir/graph/subandexpand*l*h*.m These subandexpand*l*h* take the sector decomposed integrand, and runs the subtraction and epsilon expansion, then writes the f*.f files to be numerically integrated.
USES
${graph}sec*P*l*h*.out, formindlist.m, symbsub.m, ExpOpt.m, formfortran.m USED BY subexp.pl
PURPOSE
to take the sector decomposition output, and produce f*.f files for the numerical integration
INPUTS
inserted by subexp.pl: path: directory of secdec input decomposition: reads a list of files ${graph}sec*P*l*h*.out containing the output of the decomposition n: number of propagators logi: the number of logarithmic poles in this pole structure lini: the number of linear poles in this pole structure higheri: the number of higher order poles in this pole structure partsflag: whether IBP is to be used expu: exponent of U expf: minus the exponent of F in the decomposition - integrand is numerator*(U^expu)/(F^expf) precisionrequired: order of epsilon required for result diagramname: name of the diagram subdir: subdirectory where output is placed srcdir: directory of source code variables: dieflag: is set to 1 by formindlist.m if there are no poles with this given structure time: time taken for this part of the calculation RESULT f*.f functions upto the required order are created in the appropriate directory
