Qt C++ 调用matlab生成的 dll
首先根据matlab的版本下载对应的matlab运行库
matlab 各版本运行库下载地址：
https://ww2.mathworks.cn/products/compiler/matlab-runtime.html
-------------------------------------------------------------------------------------
如我下载安装在D:\v90
配置环境变量为：

QT += core gui
QT += network
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = MatlabAxis
TEMPLATE = app
SOURCES += main.cpp\
matlabaxis.cpp \
gameserv.cpp
HEADERS += matlabaxis.h \

FORMS += matlabaxis.ui
win32: LIBS += -L$$PWD/lib/ -lSix_axis
INCLUDEPATH += $$PWD/.
DEPENDPATH += $$PWD/.
INCLUDEPATH += D:\v90\extern\include
DEPENDPATH += D:\v90\bin\win64

win32: LIBS += -L$$PWD/lib/ -lNdxDyPl
INCLUDEPATH += $$PWD/.
DEPENDPATH += $$PWD/.
-------------------------
这些就是matlab运行库要指定的
INCLUDEPATH += D:\v90\extern\include
DEPENDPATH += D:\v90\bin\win64
