    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。 <yoCW?#  
    ZWtlOP#]  
    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: pCB^\M%*  
    enableservice('AutomationServer', true) MD"a%H#p  
    enableservice('AutomationServer') $0kuR!U.N  
    +hUS sR&  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 t; 3n  
    k$ ya.b<X/  
    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: P#0U[`ltK  
    1. 在FRED脚本编辑界面找到参考. {r.KY  
    2. 找到Matlab Automation Server Type Library nV[0O8p2Md  
    3. 将名字改为MLAPP "e3T;M+  
    ;^[VqFpeS  
    #5Q?Q~E@  
    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。 >5O#_?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: slQxz;t  
    1. 创建Matlab服务器。 ~o <+tL  
    2. 移动探测面对于前一聚焦面的位置。 ~BUzyc%  
    3. 在探测面追迹光线 *y}<7R  
    4. 在探测面计算照度 3d1$w  
    5. 使用PutWorkspaceData发送照度数据到Matlab Q5ZZ4`K!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4!q4WQ ;  
    7. 用Matlab画出照度数据 ~x(1g;!^  
    8. 在Matlab计算照度平均值 vp[;rDsIJ$  
    9. 返回数据到FRED中 nDFF,ge;a#
