vars, params

Creates a vector of TPSs corresponding to each variable/parameter in the GTPSA

Syntax

x  = vars([(descriptor|tps)])
xc = complexvars([(descriptor|tps)])

k  = params([(descriptor|tps)])
kc = complexparams([(descriptor|tps)])

Description

x = vars() creates a vector of TPS64s corresponding to each of the variables in the GTPSA defined by the Descriptor in GTPSA.desc_current

x = complexvars() creates a vector of ComplexTPS64s corresponding to each of the variables in the GTPSA defined by the Descriptor in GTPSA.desc_current

k = params() creates a vector of TPS64s corresponding to each of the parameters in the GTPSA defined by the Descriptor in GTPSA.desc_current

k = complexparams() creates a vector of ComplexTPS64s corresponding to each of the parameters in the GTPSA defined by the Descriptor in GTPSA.desc_current

Optional Argument

descriptor tells vars/params to create a vector of TPSs corresponding to each of the variables/parameters in the GTPSA defined by the passed Descriptor

tps tells vars/params to create a vector of TPSs corresponding to each of the variables/parameters in the GTPSA defined by the Descriptor of the passed TPS
