    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。 %<q"&]e,  
    JO87rG  
    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: :w4H$+j  
    enableservice('AutomationServer', true) D* HK[_5  
    enableservice('AutomationServer') u7p:6W  
    bx".<q(  
    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 Jju?v2y`  
    lm'.G99{  
    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: !C.{nOfyv  
    1. 在FRED脚本编辑界面找到参考. e [F33%  
    2. 找到Matlab Automation Server Type Library zlh\P`  
    3. 将名字改为MLAPP FQJFq6l

    `lO/I+8  
    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。 _B]Bd@<w

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 6& 9q6IIy  
    1. 创建Matlab服务器。 F|WH=s3  
    2. 移动探测面对于前一聚焦面的位置。 k"FY &;G(G  
    3. 在探测面追迹光线 5bWy=Xk B  
    4. 在探测面计算照度 dp1t]  
    5. 使用PutWorkspaceData发送照度数据到Matlab -1!s8G  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 0*u X2*  
    7. 用Matlab画出照度数据 +d6Jrd*  
    8. 在Matlab计算照度平均值 T~N877  
    9. 返回数据到FRED中 lzZ=!dG
