    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。 b!5W!vcK  
    f77Jn^Dt  
    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: t_x \&+W  
    enableservice('AutomationServer', true) ,>`wz^z  
    enableservice('AutomationServer') g"hm"m}i  
    _CciU.1k&,  
    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 .1[K\t)2

    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{3He)&  
    1. 在FRED脚本编辑界面找到参考. # x!47Y{  
    2. 找到Matlab Automation Server Type Library GO+cCNMa"  
    3. 将名字改为MLAPP E Rqr0>x

    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。 +0;6.PK

    现在将脚本代码公布如下,此脚本执行如下几个步骤: TmoODG>@  
    1. 创建Matlab服务器。 uqXvN'Jr  
    2. 移动探测面对于前一聚焦面的位置。 >|/NDF=\s  
    3. 在探测面追迹光线 w(eAmN:zR  
    4. 在探测面计算照度 ZXFM_>y 5  
    5. 使用PutWorkspaceData发送照度数据到Matlab )d2 <;c  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4=%Uv^M  
    7. 用Matlab画出照度数据 S}cpYjnH8  
    8. 在Matlab计算照度平均值 C~yfuPr\B  
    9. 返回数据到FRED中 6 GO7[?U<
