Workspace

During the computation of a curve it is sometimes necessary to introduce variables and do additional computations that are common to all points of the curve. The continuer has stored the handle to the initialization and cleaning of the workspace in the variables cds.curve_init and cds.curve_done. These can be relegated to a call of the type

feval(cds.curve_init,x,v).

This option has to be provided only if the variable WorkSpace in cds.options is switched on. In this case a call

feval(cds.curve_done,x,v)

must clear the workspace. Variables in the workspace must be set global.
