It depends what you want to do with your file

If you want to read it later into Scilab you can simply use the save and 
load functions (with perform binary write and read, without loss of accuracy

If you want to read it with an other software you can use formatted 
write. for example if y is the result of your fft

//C like write
y=y(:) //make y a column vector
u=mopen("myfile","wb")
mfprintf(u,"%e %e\n",real(y), imag(y))
mclose(u)


//Fortran like write
write("myfile",[real(y), imag(y)],"(E16.9,1x,E16.9)")


Both will create a file containing the data formatted in two columns in 
each row the data are separated with a space
