求大神帮忙 关于新旧版本语句运行错误的问题

仿真321

netbp=newff([-1 1;-1 1],[2 2],{'logsig''logsig'},'traingd');

??? Error using ==> network.subsasgn>network_subsasgn
at 535
"layers{1}.transferFcn" cannot be set to non-existing
function "logsig'logsig".

Error in ==> network.subsasgn at 11
net = network_subsasgn(net,subscripts,v,netname);

Error in ==> newff>new_5p0 at 286
  net.layers{i}.transferFcn = tf{i};

Error in ==> newff>create_network at 128
  net = new_5p0(varargin{:});

Error in ==> newff at 102
  out1 = create_network(varargin{:});我知道意思是我用的语句在新版本中已改动，但应如何改？还有help应该如何用？为什么newff下的函数的例子在matlab中运行都出错？（我的是R2011b）

没用过.查了一下，可能要用feedforwardnet，在2012b里哈

奥 是  从2010b开始newff就已经被backforwardnet代替了    那请问net=newff([0 10],[5 1],{'tansig''purelin'})在新版本中应该如何用feedforwardnet写呢
