    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。 vV.'&."g  
    AS`0.RC-  
    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: ^#e:q  
    enableservice('AutomationServer', true) K) $.0S9d  
    enableservice('AutomationServer') 7qA);N  
     f]q3E[?/  
    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 Q?n} ~(% &

    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: vG#|CO9  
    1. 在FRED脚本编辑界面找到参考. ]"q[hF*PM  
    2. 找到Matlab Automation Server Type Library ~;#J&V@D  
    3. 将名字改为MLAPP z~+_sTu

    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。 @^} % o-:

    2. 移动探测面对于前一聚焦面的位置。 /L'm@8  
    3. 在探测面追迹光线 RfDIwkpp  
    4. 在探测面计算照度 CjORL'3  
    5. 使用PutWorkspaceData发送照度数据到Matlab A,e/y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 mN@)b+~(S  
    7. 用Matlab画出照度数据 r0l ud&_9  
    8. 在Matlab计算照度平均值 hE-`N,i }  
    9. 返回数据到FRED中 A2 qus$
