    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。 &HF]\`RNr  
    +VOb  
    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: Rc9<^g`  
    enableservice('AutomationServer', true) AzjMv6N   
    enableservice('AutomationServer') SMO*({/  
    TA;,>f*  
    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 j%xBo:  
    9k `~x1Y)  
    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: ^ KOzCLC  
    1. 在FRED脚本编辑界面找到参考. *{[d%B<lp  
    2. 找到Matlab Automation Server Type Library {nRUH*(d9  
    3. 将名字改为MLAPP vInFo.e[4  
    bXvbddu)}  
    >d%VDjk .  
    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 @*7B5Q

    现在将脚本代码公布如下,此脚本执行如下几个步骤: #s^s_8#&e  
    1. 创建Matlab服务器。 (j N]OE^  
    2. 移动探测面对于前一聚焦面的位置。 <%?uYCD  
    3. 在探测面追迹光线 Xw(3j)xQ  
    4. 在探测面计算照度 H m8y]>$  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;&mxqY8`'  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 O5MDGg   
    7. 用Matlab画出照度数据 j+0.= #{??  
    8. 在Matlab计算照度平均值 %UG/ak%z  
    9. 返回数据到FRED中 |[WL2<
