    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。 8Ux3,X=  
    3e+ Ih2  
    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: 0Ah'G  
    enableservice('AutomationServer', true) owHhlS{  
    enableservice('AutomationServer') jHBzZ!<  
    {gT2G*Ed^Z  
    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 T2|dFKeWG  
    %;$zR}  
    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: %g1:yx  
    1. 在FRED脚本编辑界面找到参考. K;Qlg{v  
    2. 找到Matlab Automation Server Type Library lArYlR }  
    3. 将名字改为MLAPP T{-<G13

    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。 ^t,sehpR:l

    现在将脚本代码公布如下,此脚本执行如下几个步骤: !?!~8J~  
    1. 创建Matlab服务器。 jI:5[. Y  
    2. 移动探测面对于前一聚焦面的位置。 VL4ErOoZ  
    3. 在探测面追迹光线 ]w ^9qS  
    4. 在探测面计算照度 s @\UZ C  
    5. 使用PutWorkspaceData发送照度数据到Matlab M|IR7OtLV  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 d;1%Ei3K  
    7. 用Matlab画出照度数据 Gzy"$t  
    8. 在Matlab计算照度平均值 qk!")t  
    9. 返回数据到FRED中 M_asf7|v
