    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。  wWQt  
    mv>-XJ+  
    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: G124! ^  
    enableservice('AutomationServer', true) X8y :=k,E  
    enableservice('AutomationServer') aRy" _dZ2  
    <b-OdOg  
    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 sq{=TB{

    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: SvQ!n4 $  
    1. 在FRED脚本编辑界面找到参考. :QIf0*.O  
    2. 找到Matlab Automation Server Type Library Og7^7))  
    3. 将名字改为MLAPP _6-N+FI

    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。 S/dj])g

    现在将脚本代码公布如下,此脚本执行如下几个步骤: BvP++,a&Sa  
    1. 创建Matlab服务器。 'm0_pM1:D  
    2. 移动探测面对于前一聚焦面的位置。 jHk.]4&0  
    3. 在探测面追迹光线 Ffig0K+ `  
    4. 在探测面计算照度 p ^ ONJL  
    5. 使用PutWorkspaceData发送照度数据到Matlab F},kfCFF  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 %E[ $np>  
    7. 用Matlab画出照度数据 S 9|^VU  
    8. 在Matlab计算照度平均值 =!u]t &yv  
    9. 返回数据到FRED中 >Se-5QtLcf
