如何在MATLAB中关闭所有神经网络图?

我需要显示一些网络的图，但是问题是close all不能关闭这些窗口，因此我需要运行几次后才能关闭几个窗口.

I need to show diagrams of some networks, but the problem is that close all doesn't close these windows, so I have several windows to close manually after a few runs.

[x,t] = house_dataset;
net1 = newff(x, t, [5, 3]);
view(net1);
net2 = newff(x, t, [7, 5]);
view(net2);
close all;

但是，如果我保持窗口的句柄，则close函数将其关闭:

However if I keep the handle of window, close function will close it:

net3 = newff(x, t, [9, 7]);
h = view(net3);
close(h);

但是要收集所有这些句柄对我来说并不容易.如何以编程方式找到所有这些句柄?

But it's not easy for me to collect all those handles. How can I find all those handles programmatically?
