Question

我正在尝试使用mex编译c代码。为此，我按照此链接（mathworks.com/help/matlab/ref/mex.html）中描述的两行命令运行。

copyfile(fullfile(matlabroot,'extern','examples','mex','yprime.c'),'.','f')
mex yprime.c

但是，由于以下错误导致编译失败（参见附件截图）

注意：我有matlab R2018a版本。此外，在编译之前，我通过matlab的Add-On按钮安装了MinGW-w64。我检查了gcc在路径中是否可用，我编译了另一个c代码（通过Windows命令行），以确保它编译没有问题。通过命令行编译时没有问题，但在matlab中使用mex进行编译失败。

如果你能告诉我如何解决这个问题，我将不胜感激。我也试过

mex -v yprime.c

这是调试输出
