I am doing accounts in matlab and appear 'Output truncated.  Text exceeds maximum line length of 25.000 characters for Command Window display.'
I need to view the complete answer.
What can I do?
Is possible save the answer in *.txt before of the answer appear in the display?
I tried to use simplify and not was good enough.
I am using symbolic in the matlab.
Thanks...

SymboliceEquation = ...%Here is your calculation;
f_sym = fopen('SymboliceEquation.txt', 'wt');
fprintf(f_sym, '%s\n', char(SymbolicEquation));
fclose(f_sym);
Note: char() of a symbolic expression does not generally result in a string that can be evaluated by MATLAB. char() of a symbolic expression is really only suitable for entering the expression back in to the symbolic toolbox.

Actually that will not work; it will result in a truncate display as well.

evalin(symengine, 'write', FileName, Yourvariable);

I am using MudPAD and Matlab R2007b.
I do whole accounts in Matlab, and after I use the answers in Maple for do others things/accounts.
The accounts in Maple is a other step of my problem. The use of Matlab and Maple are independents.
Thanks again.

Okay, you should be able to put the call after the end of the loop, asking to write J. But checking again, feval() is the call rather than evalin()
You may wish to consider passing through generate::optimize as well:
feval(symengine, 'write', FileName, feval(symengine, 'generate::optimize', Yourvariable));
I am not completely sure that the generated arrays will be compatible with Maple; you should run a test case. I do not have MuPAD here to experiment with.
