    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。 (D~mmffY1  
    ^&Qaf:M  
    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: lUWjm%|  
    enableservice('AutomationServer', true) K$K[fcj  
    enableservice('AutomationServer') wV(_=LF  
    6o6m"6  
    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 9N u;0  
    +/UInAM  
    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: 9K%E+_7b  
    1. 在FRED脚本编辑界面找到参考. vguqk!eo4  
    2. 找到Matlab Automation Server Type Library   (+Er  
    3. 将名字改为MLAPP I@x*>

    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。 [% 3{mAd

    现在将脚本代码公布如下,此脚本执行如下几个步骤: U8.DPRa  
    1. 创建Matlab服务器。 )_f "[m%  
    2. 移动探测面对于前一聚焦面的位置。 t,RR\S  
    3. 在探测面追迹光线 vO"AJ`_  
    4. 在探测面计算照度 Y.&z$+  
    5. 使用PutWorkspaceData发送照度数据到Matlab Ak4iG2  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 f5`exfdHE  
    7. 用Matlab画出照度数据 $R"~BZbt;  
    8. 在Matlab计算照度平均值 \)LY_D:  
    9. 返回数据到FRED中 LR`/pet
