    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。 BAS3&fA  
    V|8`]QW@  
    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: GiN\@F!  
    enableservice('AutomationServer', true) S7 Tem:/  
        enableservice('AutomationServer') D#,P-0+%  
    & ]/Z~Vt  
    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 v(tr:[V  
    >Kc>=^=5  
    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: PH}^RR{H[  
    1. 在FRED脚本编辑界面找到参考. q9&d24|  
    2. 找到Matlab Automation Server Type Library KzC`*U[  
        3. 将名字改为MLAPP mT2Fn8yC1  
         UF00K1dbz  
         Eo }mSd  
    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。 z2lEHa?w

    2. 移动探测面对于前一聚焦面的位置。 `n!<h,S'2  
    3. 在探测面追迹光线 :!f1|h  
    4. 在探测面计算照度 JUlV$b.)J  
    5. 使用PutWorkspaceData发送照度数据到Matlab .Lk2S "+  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 .{1MM8 Q  
    7. 用Matlab画出照度数据 xv{iWJcs
