    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。 F#|mN0op  
    $~T|v7Y%  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: nW]T-!  
    enableservice('AutomationServer', true) Cp#}x1{  
        enableservice('AutomationServer') uC"Gm;0  
    dEfP272M  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 ?IR+OCAA  
    3#h@,>Z;  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 9iGp0_J  
    1. 在FRED脚本编辑界面找到参考. {QT:1U \.  
    2. 找到Matlab Automation Server Type Library t#7owY$^  
        3. 将名字改为MLAPP 8VMD304  
         w=ZK=@  
         0~ cbB  
    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。 y9 K'(/

    现在将脚本代码公布如下,此脚本执行如下几个步骤: )"s(;kU!  
    1. 创建Matlab服务器。 - S%8  
    2. 移动探测面对于前一聚焦面的位置。 BSg 3  
    3. 在探测面追迹光线 IR"=8w#MP  
    4. 在探测面计算照度 (?z"_\^n/  
    5. 使用PutWorkspaceData发送照度数据到Matlab CjU?3Ag  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 :qvaI,  
    7. 用Matlab画出照度数据 C 4\Q8uK  
    8. 在Matlab计算照度平均值 'e7;^s  
    9. 返回数据到FRED中 S oB6F9
