Matlab中的imagesc和imshow bug，太奇怪了

看来我的imshow和imagesc有问题

c = [1, 2; 3, 4];
imagesc(c);

结果:

    Error using setdiff
    Too many input arguments.

    Error in clo (line 49)
                kids_to_delete = setdiff(findall(obj,'serializable','on','-depth',1),obj,'legacy');

    Error in cla (line 29)
    clo(ax, extra{:});

    Error in newplot>ObserveAxesNextPlot (line 125)
        cla(ax, 'reset',hsave);

    Error in newplot (line 74)
    ax = ObserveAxesNextPlot(ax, hsave);

    Error in imagesc (line 19)
        hh = image(varargin{1},'CDataMapping','scaled');

 Error using setdiff
    Too many input arguments.

Error in clo (line 49)
            kids_to_delete = setdiff(findall(obj,'serializable','on','-depth',1),obj,'legacy');

Error in cla (line 29)
clo(ax, extra{:});

Error in newplot>ObserveAxesNextPlot (line 125)
    cla(ax, 'reset',hsave);

Error in newplot (line 74)
ax = ObserveAxesNextPlot(ax, hsave);

Error in basicImageDisplay (line 24)
    hh = image(cdata, ...

Error in imshow (line 266)
  hh = basicImageDisplay(fig_handle,ax_handle,...

当我试图展示时：

c = [1, 2; 3, 4];
imshow(c);

结果:

    Error using setdiff
    Too many input arguments.

    Error in clo (line 49)
                kids_to_delete = setdiff(findall(obj,'serializable','on','-depth',1),obj,'legacy');

    Error in cla (line 29)
    clo(ax, extra{:});

    Error in newplot>ObserveAxesNextPlot (line 125)
        cla(ax, 'reset',hsave);

    Error in newplot (line 74)
    ax = ObserveAxesNextPlot(ax, hsave);

    Error in imagesc (line 19)
        hh = image(varargin{1},'CDataMapping','scaled');

我现在使用的是win-64bit，MatLab R2013b，这个问题似乎发生了好几次，在我重新安装MatLab后可以解决。

您是否尝试过关闭所有图形（使用

关闭所有

）？还是重新启动Matlab？@LuisMendo Yep，没有运气。试试

哪个setdiff

-在你的Matlab路径上是否有另一个名为

setdiff

的文件隐藏了内置函数？
