mxArray指针的变量名称

Question

是否可以获取mxArray指针的变量名？

const char * strFileMatFile = "path/to/mat/file.mat";
pMatFile = matOpen(strFile, "r");

const char * strVarName = "a" // name of a variable inside the mat file
                              // which I want to find with the mxArray pointer
// Get a pointer to the variable with name strVarName in the mat file
mxArray *pVariable = matGetVariable(pMatFile, strVarName);


const char * strVarNameFromPtr = mxArrayToString(pVariable);

mxArrayToString(pVariable)返回null。是否有一个函数可以返回mxArray指针的变量名？

类似的东西：

const char * strVarNameFromPtr = mxGetName(pVariable);
