    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。 PT`];C(he  
    `oDs]90  
    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: T7wy{;  
    enableservice('AutomationServer', true) ~^6[SbVb  
    enableservice('AutomationServer') K`BNSdEN>  
    7wO0d/l_  
    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 dn"&j1@KY

    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: W(C\lSE0  
    1. 在FRED脚本编辑界面找到参考. tHvc*D  
    2. 找到Matlab Automation Server Type Library M[;N6EJH  
    3. 将名字改为MLAPP 5W T^;J9V

    zF%'~S0{  
    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。 DE0gd ux8

    现在将脚本代码公布如下,此脚本执行如下几个步骤: C4#EN}  
    1. 创建Matlab服务器。 L\:f#b~W  
    2. 移动探测面对于前一聚焦面的位置。 B@:11,.7  
    3. 在探测面追迹光线 t Q0vX@I<v  
    4. 在探测面计算照度 ZPM,ZGlu:  
    5. 使用PutWorkspaceData发送照度数据到Matlab zoj3w|G  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &WqKsH$  
    7. 用Matlab画出照度数据 wRc=;f  
    8. 在Matlab计算照度平均值 oicj3xkw?  
    9. 返回数据到FRED中 TAkM-iyH]
