the precedent mail was poorly rendered, here it goes again without fancy 
formating :

//I would recommend to drop the "===", so the file is much easier to parse

function mybetterexport(varname)
     matval = evstr(varname);
     [n m] = size(matval);

     output = emptystr(n+1,m);  //n+3 if you
     // output = emptystr(n+3,m);  //if you really need the =====
     output(1,1) = varname;
     output(2:$,:) = string(matval);
     // output(3:$-1,:) = string(matval);
     // output([2 $],:) = "="

     write_csv(output,varname+".tsv") //you should be able to open the 
tsv file with excel, in a very convinient way. you can use any notepad too
endfunction

foo=rand(3,5);

//two ways to use the functions
mybetterexport foo
mybetterexport("foo");

//lets read the generated file
[ val txt] = fscanfMat ("foo.tsv") //this function will parse "foo.tsv" 
very very quickly

//which allows :
function mybetterimport(varname)
     [ val txt] = fscanfMat (varname+".tsv") //very useful !

     if varname~=stripblanks(txt,%t)   //paranoid check, you could drop 
this an rely on the filename
         error("file corrupted")
     end
     disp(varname+" will be loaded to scilab")
     execstr("["+varname+"]=return(val)")  //if you want to understand 
this wizzard stuff, try "help execstr" and "help return", and also 
http://wiki.scilab.org/howto/global%20and%20local%20variables
endfunction

clear foo //forgets foo
mybetterimport foo
mybetterimport("foo")
foo //this is total magic
