    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。 _wvSLu<q  
    6Ja } 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: %5) 1^  
    enableservice('AutomationServer', true) 0[ (Z48  
    enableservice('AutomationServer') kH&KE5  
     ]I pLF#  
    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 }ZPO^4H;-  
    '!$g<= @  
    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: @(k}q3b<  
    1. 在FRED脚本编辑界面找到参考. ?_hKhn%K9  
    2. 找到Matlab Automation Server Type Library Q7<_> )e^  
    3. 将名字改为MLAPP tXlo27J

    CC8M1iW3  
    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。 soSdlV{

    现在将脚本代码公布如下,此脚本执行如下几个步骤: /&PRw<}>_o  
    1. 创建Matlab服务器。 ar+ j`QIe  
    2. 移动探测面对于前一聚焦面的位置。 pb>TUKvT&  
    3. 在探测面追迹光线 (4;m*' X  
    4. 在探测面计算照度 NI^=cN,l  
    5. 使用PutWorkspaceData发送照度数据到Matlab "4`i]vy8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ]VuB2L[D  
    7. 用Matlab画出照度数据 D's Tv}P  
    8. 在Matlab计算照度平均值 R&lJ& SgC  
    9. 返回数据到FRED中 }8joltf
