简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 *mw *z|-^V T0o0_R 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: +wGvYr
enableservice('AutomationServer', true) Fbw.Y6 enableservice('AutomationServer') R_80J=%0 n482?Wp 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 \Jwc[R&x p8iKZI]g 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: >+%0|6VSb 1. 在FRED脚本编辑界面找到参考. 8y4t9V 2. 找到Matlab Automation Server Type Library "`KT7 3. 将名字改为MLAPP 2%-/}'G* ]~pM;6Pu0 B}I9+/|{ 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 bhKe"#m|S XCGK&OGI 图 编辑/参考 k5X-*^U=V} `@&WELFv{ 现在将脚本代码公布如下,此脚本执行如下几个步骤: MdnapxuS 1. 创建Matlab服务器。 XS>( Bu 2. 移动探测面对于前一聚焦面的位置。 N.V5>2 3. 在探测面追迹光线 ~kI$8oAry 4. 在探测面计算照度 S:cd'68D 5. 使用PutWorkspaceData发送照度数据到Matlab S<I9`k G 6. 使用PutFullMatrix发送标量场数据到Matlab中 wk2Ff*& 7. 用Matlab画出照度数据 4=njM`8Y' 8. 在Matlab计算照度平均值 8wCB}q C 9. 返回数据到FRED中 "Qk)EY ka$la;e3 代码分享:
