    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。 O]VHX![Y$  
    P+<4w  
    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: /{%p%Q[X  
    enableservice('AutomationServer', true) -J]j=  
    enableservice('AutomationServer') 7N4)T'B  
    Z3qr2/  
    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 d3jzGJrU}

    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: M'5PPBSR  
    1. 在FRED脚本编辑界面找到参考. 'aqlNBG*  
    2. 找到Matlab Automation Server Type Library ArVW2gL  
    3. 将名字改为MLAPP m bZn[D_zi

    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。 M.u1SB0

    现在将脚本代码公布如下,此脚本执行如下几个步骤: JsK_q9]$e  
    1. 创建Matlab服务器。 kHz?vVE/l  
    2. 移动探测面对于前一聚焦面的位置。 5H }d\=z  
    3. 在探测面追迹光线 moCr4*jDX,  
    4. 在探测面计算照度 %v)+]Ds{  
    5. 使用PutWorkspaceData发送照度数据到Matlab /K :H2?J  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ',m!L@7M5  
    7. 用Matlab画出照度数据 WGA"e   
    8. 在Matlab计算照度平均值 +HkEbR'G0  
    9. 返回数据到FRED中 `dJ?j[P,p
