    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。 ^B<PD]  
    f gK2.;>  
    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: >tmnj/=&   
    enableservice('AutomationServer', true) EBj,pk5M  
    enableservice('AutomationServer') 33{;[/4  
    .fLiXx  
    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 /^z/]!JG:V  
    k lP{yxU'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: oN&rq6eN  
    1. 在FRED脚本编辑界面找到参考. Y'<uZl^aX  
    2. 找到Matlab Automation Server Type Library _ bXVg3oDt  
    3. 将名字改为MLAPP E !Oz|q

    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。 3P+4S|@q(4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: -(/2_&"  
    1. 创建Matlab服务器。 ]b0zkoD9<  
    2. 移动探测面对于前一聚焦面的位置。 IL+#ynC  
    3. 在探测面追迹光线 O:`GL1{ve?  
    4. 在探测面计算照度 AND7jEn  
    5. 使用PutWorkspaceData发送照度数据到Matlab K)Df}fVOc  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 */%$6s~  
    7. 用Matlab画出照度数据 `G"|MM>P  
    8. 在Matlab计算照度平均值 Xmf  
    9. 返回数据到FRED中 U,%s;
