    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。 ~`B]G  
    ^!n|j]aw  
    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: %T\ 2.vl  
    enableservice('AutomationServer', true) F2EX7Crj  
    enableservice('AutomationServer') ,ei=w,O  
    _{eA8J(A<  
    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 vL^ +X`.td

    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: 3"k n5)x  
    1. 在FRED脚本编辑界面找到参考. !;hp  
    2. 找到Matlab Automation Server Type Library Mm9*$g!R  
    3. 将名字改为MLAPP -z se+]O`

    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。 peOoZdJd

    现在将脚本代码公布如下,此脚本执行如下几个步骤: B7.&yXWgn  
    1. 创建Matlab服务器。 {k[dg0UV  
    2. 移动探测面对于前一聚焦面的位置。 [ q[2\F?CE  
    3. 在探测面追迹光线  a3a:H  
    4. 在探测面计算照度 P_75-0G  
    5. 使用PutWorkspaceData发送照度数据到Matlab s~ o\j/  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {SRD\&J[  
    7. 用Matlab画出照度数据 ,]das  
    8. 在Matlab计算照度平均值 kmtkh "  
    9. 返回数据到FRED中 ?U1Nm~'UZ
