    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。 RoZV6U~  
    $ 1ZY Vw  
    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: rkl7p?  
    enableservice('AutomationServer', true) CG;D(AWR;  
    enableservice('AutomationServer') ?#m5$CFp  
    h@d m:=ul  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Xv:IbM> Qc  
    wQc  w#  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: LAeXe!y  
    1. 在FRED脚本编辑界面找到参考. k_B^2=  
    2. 找到Matlab Automation Server Type Library  .@Cshj  
    3. 将名字改为MLAPP #v-!GK_<  
    ?Dm&A$r  
    yNL71>w4  
    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。 <9~qAq7^

    现在将脚本代码公布如下,此脚本执行如下几个步骤: -tQ|&fl  
    1. 创建Matlab服务器。 i}19$x.D`  
    2. 移动探测面对于前一聚焦面的位置。 9':$!Eoq  
    3. 在探测面追迹光线 A-FwNo2"%  
    4. 在探测面计算照度 Y$^\D' .k  
    5. 使用PutWorkspaceData发送照度数据到Matlab K~]jXo^M  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 guvQISQlY  
    7. 用Matlab画出照度数据 /v[- KjTj7  
    8. 在Matlab计算照度平均值 \bfHGo=  
    9. 返回数据到FRED中 _f`m/l
