    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。 sx7zRw >X  
    vc3r [mT  
    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: L;?h)8  
    enableservice('AutomationServer', true) t~ I;IB  
    enableservice('AutomationServer') ~$^ >Vo  
    *v8daF  
    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  <{ v %2

    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: WB'1_a  
    1. 在FRED脚本编辑界面找到参考. qo \9,<  
    2. 找到Matlab Automation Server Type Library rrgOp5aV"  
    3. 将名字改为MLAPP $A,YQH+  
    [h B$%i]\<  
    /L(}VJg-  
    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。 2)$-L'YS

    现在将脚本代码公布如下,此脚本执行如下几个步骤: F_w+8)DZ  
    1. 创建Matlab服务器。 )+,h}XqlX  
    2. 移动探测面对于前一聚焦面的位置。 lJfk4 -;M  
    3. 在探测面追迹光线 *m>[\)  
    4. 在探测面计算照度 DS@Yto  
    5. 使用PutWorkspaceData发送照度数据到Matlab =5^1Bl  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 K3=0D!Dq  
    7. 用Matlab画出照度数据 jvR(e"  
    8. 在Matlab计算照度平均值 H ~fF; I  
    9. 返回数据到FRED中 ^  ~1QA
