在Python中使用Matlab用户函数会产生错误
我有用户Matlab函数。这是别人写的。该文件中有多个函数,但与.m文件itsel同名的第一个函数是我尝试调用的函数。它得到4个参数(字符串、字符串、字符串、布尔值)。 通常在Matlab中我这样称呼它:函数('string','string,true) 在Python中尝试时,我使用以下代码在Python中使用Matlab用户函数会产生错误,matlab,python-3.6,matlab-engine,Matlab,Python 3.6,Matlab Engine,我有用户Matlab函数。这是别人写的。该文件中有多个函数,但与.m文件itsel同名的第一个函数是我尝试调用的函数。它得到4个参数(字符串、字符串、字符串、布尔值)。 通常在Matlab中我这样称呼它:函数('string','string,true) 在Python中尝试时,我使用以下代码 def CodeGenerationAndResim(self, Models=None, Resim=False, Type='TW'): """ This function will star

return MatlabEngineSuccessfull, CodeGenSuccessfull, ResimSuccessfull
我得到的错误如下:
Error using resimPrepareNewVersion
Too many output arguments.
Too many output arguments.
我不明白这个错误。我已经给出了与Matlab中相同的参数。即使我给它3,2,或者没有参数,我也会得到同样的错误。当Matlab加载时,这些函数会自动加载,所以我不需要添加路径,但我用了任何方法。然而,我没有给出任何途径就尝试了。代码生成和启动Matlab没有任何问题。在Matlab中,此函数加载一些其他文件并打开一个信息对话框,它意味着任何东西。真奇怪,我一直将错误标记为
输入参数太多,而不是输出参数
我通过插入nargout=0
解决了这个问题
编辑:
matlabEngine.resimPrepareNewVersion('all','DAS2_TwYYWW_2005',1)
致:
而且效果很好。谢谢
matlabEngine.resimPrepareNewVersion('all','DAS2_TwYYWW_2005',1, nargout=0)
