    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。 {9cjitl  
    1=PTiDMJ<*  
    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: c/l^;6O/!\  
    enableservice('AutomationServer', true) YU\k D  
    enableservice('AutomationServer') Sf2xI'  
    ,G[Y< ~Hy  
    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 FJn.V1

    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: b&9~F6aM  
    1. 在FRED脚本编辑界面找到参考. P#[?Kfi  
    2. 找到Matlab Automation Server Type Library bYr*rEcA  
    3. 将名字改为MLAPP RSnBG"  
    vdot .

    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。 F(Je$c/J|~

    d-z[=1m  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: N@^:IfJ+=  
    1. 创建Matlab服务器。 '($$-P\/  
    2. 移动探测面对于前一聚焦面的位置。 2q*wYuc  
    3. 在探测面追迹光线 F 1l8jB\  
    4. 在探测面计算照度 `v)ZOw9&  
    5. 使用PutWorkspaceData发送照度数据到Matlab F45-M[z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 20I/En  
    7. 用Matlab画出照度数据 pnXwE-c_  
    8. 在Matlab计算照度平均值 jsP+,brO  
    9. 返回数据到FRED中 ')Y1c O
