    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。 r4NI(\gU  
    uW4G!Kw28  
    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: -w 2!k  
    enableservice('AutomationServer', true) _h_;nS.Y  
    enableservice('AutomationServer') =,-80WNsX  
    | x{:GWq  
    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 M#})  
    xpFu$2T6P.  
    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: c R$2`:e  
    1. 在FRED脚本编辑界面找到参考. *%ZfE,bu8<  
    2. 找到Matlab Automation Server Type Library ({![  
    3. 将名字改为MLAPP 8nES=<rz

    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。 gU>Y

    2. 移动探测面对于前一聚焦面的位置。 t>&$_CSWK  
    3. 在探测面追迹光线 t K{`?NS  
    4. 在探测面计算照度 l/LRr.x  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2K, 1wqf'  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Xa<siA{  
    7. 用Matlab画出照度数据 FO3!tJ\L
