    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。 4.7ePbk[E  
    S@zsPzw  
    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: gydPy*  
    enableservice('AutomationServer', true) PK u+$  
        enableservice('AutomationServer') UR?[ba_h   
    )[6H!y5  
    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 8p7Uvn+m*  
    ;t@zH+*}  
    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: oa+Rr&t'  
    1. 在FRED脚本编辑界面找到参考. W\zg#5fmK  
    2. 找到Matlab Automation Server Type Library -ny[Lh^b  
        3. 将名字改为MLAPP =_8  
         :a3Pnq$]E  
         JcZs\ fl9  
    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。 j%b/1@I

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ow ~(k5k:  
    1. 创建Matlab服务器。 F`U%xn,  
    2. 移动探测面对于前一聚焦面的位置。 ^l ~i>:V  
    3. 在探测面追迹光线 R1X9  
    4. 在探测面计算照度 f>5{SoM  
    5. 使用PutWorkspaceData发送照度数据到Matlab 1Af~6jz  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 j"/i+r{"E  
    7. 用Matlab画出照度数据 _5.^A&Y*  
    8. 在Matlab计算照度平均值 [a 5L WW  
    9. 返回数据到FRED中 Xf9<kbRw/
