    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。 j<p.#jkT  
    _? gCOr  
    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: pZnp!!G  
    enableservice('AutomationServer', true) +X=*>^G(-  
        enableservice('AutomationServer') g_Z tDxz  
    h@Q^&%w  
    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 nq M7Is  
    3v8LzS3@  
    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: DzAZv/h76  
    1. 在FRED脚本编辑界面找到参考. *&NP?-E  
    2. 找到Matlab Automation Server Type Library RuPnWx!  
        3. 将名字改为MLAPP .e~"+Pe6b  
         L'= \|r  
         4Z)s8sDKW  
    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。 $'J3 /C7

    现在将脚本代码公布如下,此脚本执行如下几个步骤: %_OjmXOfe  
    1. 创建Matlab服务器。 X94a  
    2. 移动探测面对于前一聚焦面的位置。 m{/7)2.  
    3. 在探测面追迹光线 ^jL '*&l  
    4. 在探测面计算照度 |6E_N5~  
    5. 使用PutWorkspaceData发送照度数据到Matlab ORExI.<`W  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 n Nt28n@  
    7. 用Matlab画出照度数据 :7v'[b  
    8. 在Matlab计算照度平均值 \ 2\{c1df  
    9. 返回数据到FRED中 2*: q$c
