    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。 cOUO_xp(  
     bM-Y4[  
    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: @Rx/]wyH  
    enableservice('AutomationServer', true) |Cen5s W&  
    enableservice('AutomationServer') "%.#/!RG  
    .IKK.G  
    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 aB'<#X$x  
    cA/2,i  
    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: c89RuI `B~  
    1. 在FRED脚本编辑界面找到参考. $iP#8La:Y  
    2. 找到Matlab Automation Server Type Library e,4!/|H:  
    3. 将名字改为MLAPP + u)'

    @{ nT4{  
    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。 mB1)!

    现在将脚本代码公布如下,此脚本执行如下几个步骤: _8S).*  
    1. 创建Matlab服务器。 W:) M}}&H  
    2. 移动探测面对于前一聚焦面的位置。 Ko%rB+d  
    3. 在探测面追迹光线 [j![R  
    4. 在探测面计算照度 @C!q S7k)  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,U7hzBj8k  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 AVcZ.+?  
    7. 用Matlab画出照度数据 st+Kz uK  
    8. 在Matlab计算照度平均值 xeHu-J!P  
    9. 返回数据到FRED中 gq0gr?
