Summary

In the following table we list calls that can be made to the continuation curve description cds and which options are involved.

Syntax of call	What it should do (options involved)
feval(cds.curve_func,x)	return $F($x$)$
feval(cds.curve_options)	return option vector
feval(cds.curve_jacobian,x)	return Jacobian at x (SymDerivative$\geq 1$)
feval(cds.curve_hessians,x)	return Hessians at x (SymDerivative$\geq 2$)
feval(cds.curve_init,x,v)	initialize user variable space (WorkSpace)
feval(cds.curve_done)	destroy user variable space (WorkSpace)
feval(cds.curve_defaultprocessor,x,v,s)	initialize data for testfunctions and
	set some general singularity data
feval(cds.curve_testf,ids,x,v)	return evaluation of testfunctions ids at x
	(Singularities)
feval(cds.curve_locate,i,x1,x2,v1,v2)	return located singularity and tangent
	vector(Locators)
feval(cds.curve_userf,UserInfo,ids,x,v)	return evaluation of userfunctions ids with
	UserInfo at x (Userfunctions)
feval(cds.curve_singmat)	return singularity matrix (Singularities)
feval(cds.curve_process,i,x)	run processor code of singularity i
	at x(Singularities)
feval(cds.curve_adapt,x,v)	run adaptation code of problem (Adapt)
