    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。 lQ<#jxp  
    *@G(3 n  
    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: qSC~^N`  
    enableservice('AutomationServer', true) \p3nd!OIG  
    enableservice('AutomationServer') ^E<~zO=Z  
    {GX &)c4  
    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 !|Xl 8lV`  
    <^*+8{*  
    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: )Vg{Y [!  
    1. 在FRED脚本编辑界面找到参考. >xU72l#5  
    2. 找到Matlab Automation Server Type Library k{}[>))Q  
    3. 将名字改为MLAPP y\|-O<8O

    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。 fUp|3bBE

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :_fjml/  
    1. 创建Matlab服务器。 i^yH?bH @~  
    2. 移动探测面对于前一聚焦面的位置。 gf3u0' $  
    3. 在探测面追迹光线 +9 16ZPk  
    4. 在探测面计算照度 liugaRO8J  
    5. 使用PutWorkspaceData发送照度数据到Matlab - 5o<Q'(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ^:cb $9F  
    7. 用Matlab画出照度数据 o&hKg#nO83  
    8. 在Matlab计算照度平均值 y?*[}S  
    9. 返回数据到FRED中 _>jrlIfc
