    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。 RQxL`7H  
    HO[W2b  
    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: qg1s]c~0u  
    enableservice('AutomationServer', true) }zC9;R(E  
    enableservice('AutomationServer') ;]c@%LX  
    p_%dH  
    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 ehCGu( =

    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: 9/2VU< K  
    1. 在FRED脚本编辑界面找到参考. -([ ipg(r  
    2. 找到Matlab Automation Server Type Library y0s=yN_  
    3. 将名字改为MLAPP Z 0&=Lw

    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。 jMUd,j`Opx

    现在将脚本代码公布如下,此脚本执行如下几个步骤: |pLx,#n  
    1. 创建Matlab服务器。 #<h//<  
    2. 移动探测面对于前一聚焦面的位置。 x -;tV=E}  
    3. 在探测面追迹光线 0b=1Ce+0q  
    4. 在探测面计算照度 (|O9L s7N  
    5. 使用PutWorkspaceData发送照度数据到Matlab Q$,AQyBlqc  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 |m{u]9  
    7. 用Matlab画出照度数据 vq?Lej  
    8. 在Matlab计算照度平均值 [}>!$::Y  
    9. 返回数据到FRED中 phCItN;
