C++调用matlab引擎画三维图

VS2012设置

项目–项目属性–配置属性–VC++目录–包含目录 D:\MATLAB\R2016a\extern\include

项目–项目属性–配置属性–VC++目录–库目录
D:\MATLAB\R2016a\extern\lib\win64\microsoft

添加依赖项有两种方法：

方法一：项目中设置

项目–项目属性–配置属性–链接器–输入–添加依赖项
libmx.lib
libmat.lib
libmex.lib
mclmcr.lib
mclmcrrt.lib
libemlrt.lib
libeng.lib
libfixedpoint.lib
libcovrt.lib

方法二：程序中添加

#pragma comment(lib,“libmx.lib”)
#pragma comment(lib,“libmat.lib”)
#pragma comment(lib,“libmex.lib”)
#pragma comment(lib,“mclmcr.lib”)
#pragma comment(lib,“mclmcrrt.lib”)
#pragma comment(lib,“libemlrt.lib”)
#pragma comment(lib,“libeng.lib”)
#pragma comment(lib,“libfixedpoint.lib”)
#pragma comment(lib,“libcovrt.lib”)

计算机–属性–高级系统设置–环境变量–系统变量–Path–新建
D:\MATLAB\R2016a\bin\win64

运行结果

说明

VS2012新建名称为“matlab”项目，在“matlab”项目文件夹下新建figure文件夹，figure文件夹中放matlab画图程序 pt.m。
VS2012编译平台选择与matlab版本对应起来，文章选择的是64位。
