    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。 6)^*DJy  
    fF0K].  
    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: W8g13oAu"  
    enableservice('AutomationServer', true) 5_!L"sJ  
    enableservice('AutomationServer') YdCl  
    h2zSOY{su  
    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 Eq)b=5qrG?

    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: F7=9> ,  
    1. 在FRED脚本编辑界面找到参考. `C>h]H(  
    2. 找到Matlab Automation Server Type Library $=plAi  
    3. 将名字改为MLAPP LOkgeJuWv

    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。 R9A:"sJ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: n8EKTuy  
    1. 创建Matlab服务器。 z#Jw?K_  
    2. 移动探测面对于前一聚焦面的位置。 i`@cVYsL  
    3. 在探测面追迹光线 P[ o"%NZ'  
    4. 在探测面计算照度 !6|_`l>G,  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2*D2jw  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 m%J?5rR3  
    7. 用Matlab画出照度数据 [ 6VM4l"  
    8. 在Matlab计算照度平均值 c_qox  
    9. 返回数据到FRED中 ^IiA(?8
