DEInt.setParams

Initialize an object for computing DE integration.

void setParams(F xa, F xb, Flag!"isExpType" isExpType = No.isExpType, size_t trapN = 0, F ta = F.nan, F tb = F.nan)

Parameters

xa: Type: F
starting value of original integration.
xb: Type: F
end value of original integration.
isExpType: Type: Flag!"isExpType"
if the integration is formed as int_a^b f(x) exp(-x) dx, this value is Yes. otherwise No.
trapN: Type: size_t
division points of trapezoidal quadrature. If this value is 0, 100 is used internally.
ta: Type: F
starting value of integration transformed by DE-formula. If this value is NaN, -5 is used internally.
tb: Type: F
starting value of integration transformed by DE-formula. If this value is NaN, +5 is used internally.
