Try to increase maxfun limit. For example,

dsolve({odesys, initcond}, ..., numeric, method=rkf45, maxfun=1000000);

If you specify maxfun=0 the maxfun limit will be completely turn off.

@Carl Love Thank you for the answer. I understand so it is a hopeless situation. It's a pity.

Oh. Thank you very much. "currentdir()" is exactly what I want. Thanks a lot.

Thank you very much for the reply.
But the problem still isn't solved becouse changing of file names isn't good way. As a result I will have a confusion with files. I need save results in the same directory from where Maple code is run. How does it do?

Does anyone know how to send a variable from terminal or windows command line to Maple?

Thank you very much for the reply.

Thanks a lot. Your suggestion is turned out very useful for me. Now I understand how to finish with it.

Try now:

Thank you very much for the help.

You don't understand me a little. I need to add a new matrix to previous one which has already saved in the textfile.
Another words in my case it will be work if after exporting first matrix to the textfile uses

a restart command. But when I use exportmatrix command the last matrix overwrites previous one.
