Solution in a tabular form
In EpODE, the approximate solution values computed at each step
integration step are saved in the computation process. The allocation of the necessary storage space
is made dynamically. A preliminary test for the storing capacity is
made in order to adapt the number of the stored values if the number
of stored values will be too big to fit in the available memory.
A special function was designed to access any value of the approximate
solution. Since in the general case (for drawing or for tabular presentation)
these values are acceded sequentially, in the storing order, a special
pointer points to the last acceded value.
Two variants of tabular presentation of the approximate solution were adopted
in EpODE:
- for the values of the approximate solution at the end of the integration interval;
- for all values of the approximate solution, presented in the computation order.
The components of the approximate solution which will appear in the table
can be selected from the list of all components (including also the independent variable).
