Error when using writeif statement

Asked by Jessica
on 16 Jul 2012
Hi, I am translating code from Fortran to Matlab with a converter and I get an error of "Unexpected MATLAB operator" in the following part:
for t = 1: ntime
for j = 1: nequation(t);
k = eqindex(t,j);
writef(fid_1,[repmat('%i',1,2),repmat('%16.8f',1,<)],t,k, beta(t,k,:), z(t,k,:), h(t,k,k));
writef(fid_1,[repmat('%i',1,2),repmat('%16.8f',1,<)],t,k,sdbeta(t,k,:),sdz(t,k,:),sdh(t,k,k));
writef(fid_1,['%0.15g \n']);
end;
writef(fid_1,['%0.15g \n']);
end;
Could someone please guide me as to what I am doing wrong?
Thanks,
Jessica

[EDITED 2, copied from Answers section, please care for a proper formatting]:
Thanks for your quick answers. I guess my main problem is that I am translating from Fortran with this converter and this is the output which I got, which I know makes no sense. Does anyone know Fortran and Matlab? In Fortran the code is:
do t = 1ntime do j = 1, nequation(t) k = eqindex(t,j) write(1,'(2I,<nx+nfac+1>f16.8)')t,k, beta(t,k,:), Z(t,k,:), H(t,k,k) write(1,'(2I,<nx+nfac+1>f16.8)')t,k,sdbeta(t,k,:),sdZ(t,k,:),sdH(t,k,k) write(1,*) end do write(1,*) end do close(1)

Please follow the "About MATLAB Answers" link to learn, how to format your code. It is hard to decide, if the line breaks are inserted by the forum layout or if they exist in the real source code also.
I find "writef" in the code, but "writeif" in the subject and the tags. I've modified the tag already.
Whenever you post an error message here, copy it completely. Especially the line, which causes the error, is very helpful.

Please, Jessica, learn how to use the "{} Code" button to format code. And please add information required to understand the question by editing the question, not by posting an answer. Thanks.

You are probably looking for fprintf or fwrite.
doc fprintf
doc fwrite

Beside that fact, that Matlab does not have a writef function, the expression:
repmat('%16.8f',1,<)
is not valid in Matlab. The "<" is obviously unexpected. What should happen here?
Did you ask the author of the converter already? What did he reply?
