    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。 SxT:k,ji  
    mbS &>  
    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: c yN_Sg  
    enableservice('AutomationServer', true) kP;Rts8JD  
    enableservice('AutomationServer') 5gJQr%pS  
    23+GX&Rp  
    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 ]m}>/2oSs

    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: >J8?n,*  
    1. 在FRED脚本编辑界面找到参考. !4z"a@$  
    2. 找到Matlab Automation Server Type Library vkR"A\:  
    3. 将名字改为MLAPP @69q// #B

    C8G['aQ  
    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。 , H[o.r=

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  R6AZIN:  
    1. 创建Matlab服务器。 + qS$t  
    2. 移动探测面对于前一聚焦面的位置。 fYCAwS{  
    3. 在探测面追迹光线 +pjD{S~Y  
    4. 在探测面计算照度 jliKMd<?  
    5. 使用PutWorkspaceData发送照度数据到Matlab e@Mm4&f[p  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 %|,j'V$  
    7. 用Matlab画出照度数据 \< z{ @  
    8. 在Matlab计算照度平均值 `,7BU??+u  
    9. 返回数据到FRED中 C(gH}N4
