    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。 LA/Qm/T  
    %`/F> `  
    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: "%_T7 A ![  
    enableservice('AutomationServer', true) XCXX(8To0=  
    enableservice('AutomationServer') cBZJ  
    cveQ6 -`K  
    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 1jPh0?BY

    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: +4[9Eb'k=  
    1. 在FRED脚本编辑界面找到参考. >5 Y.  
    2. 找到Matlab Automation Server Type Library @,W5K$Ka=  
    3. 将名字改为MLAPP :<5jlpV(  
    :j/sTO=  
    jL'R4z  
    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。 ;Uy}(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: d%E*P4Ua  
    1. 创建Matlab服务器。 w2lO[o~x}  
    2. 移动探测面对于前一聚焦面的位置。 l2Rnyb<;;  
    3. 在探测面追迹光线 x>T+k8[n  
    4. 在探测面计算照度 3Lv5>[MnN  
    5. 使用PutWorkspaceData发送照度数据到Matlab T~g`;Q%i  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xjrL@LO#  
    7. 用Matlab画出照度数据 ~K(mt0T )  
    8. 在Matlab计算照度平均值 % ;a B#:p6  
    9. 返回数据到FRED中 ?<Mx*l
