    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。 .5G`Y  
    mYgfGPF`  
    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: ?<!q F:r:  
    enableservice('AutomationServer', true) -t|/g5.w_  
    enableservice('AutomationServer') 3Xu|hkK\e  
    ;F"!$Z/  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Cj8&wz}ez  
    ewk7:zS/?  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: I!Z`'1"  
    1. 在FRED脚本编辑界面找到参考. T(*,nJi~9  
    2. 找到Matlab Automation Server Type Library B-C$>H^  
    3. 将名字改为MLAPP 05FGfnq.8

    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。 Th9V8Rg+E

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Z2$_9.  
    1. 创建Matlab服务器。 <x^$Fu  
    2. 移动探测面对于前一聚焦面的位置。 sq_>^z3T  
    3. 在探测面追迹光线 |})s0TU  
    4. 在探测面计算照度 2 L4[~>  
    5. 使用PutWorkspaceData发送照度数据到Matlab N^rpPq  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 p<r<Y %  
    7. 用Matlab画出照度数据 hc|A:v)]  
    8. 在Matlab计算照度平均值 k-|g  
    9. 返回数据到FRED中 Qjj }k)
