    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。 5a&BgBO1M  
    B?l 0u  
    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: k)R~o b  
    enableservice('AutomationServer', true) vj9'5]!~q  
        enableservice('AutomationServer') _*ar\A`  
    upnX7as  
    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 35J VF*z  
    k)9+;bKQQ  
    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: Vsr"W@k_  
    1. 在FRED脚本编辑界面找到参考. &v#pS!UOj  
    2. 找到Matlab Automation Server Type Library !P3y+;S  
        3. 将名字改为MLAPP 7(d#zu6n  
         &"( zK"O  
         WO6R04+WV  
    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。 E24j(>

    现在将脚本代码公布如下,此脚本执行如下几个步骤: jq%}=-%KE  
    1. 创建Matlab服务器。 $,B;\PX  
    2. 移动探测面对于前一聚焦面的位置。 0g9y4z{H  
    3. 在探测面追迹光线 f@2F!  
    4. 在探测面计算照度 +j %y#_~  
    5. 使用PutWorkspaceData发送照度数据到Matlab C3'?E<F  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 iBwM]Eyv.  
    7. 用Matlab画出照度数据 hj}PL  
    8. 在Matlab计算照度平均值 V|~o`(]  
    9. 返回数据到FRED中 Lp(i&A
