    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。 'uEl~> l7  
    AYx{U?0p  
    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: N87B8rDl  
    enableservice('AutomationServer', true) B^9j@3Ux  
    enableservice('AutomationServer') ?6Y?a2 |  
    rw #$lP  
    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 {/:x5l8  
    M =r)I~  
    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: ^y%T~dLkp'  
    1. 在FRED脚本编辑界面找到参考. }vM("v|M  
    2. 找到Matlab Automation Server Type Library ')3 bl3:  
    3. 将名字改为MLAPP IO-Ow!

    &.?'i1!  
    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。 d>C$+v>

    现在将脚本代码公布如下,此脚本执行如下几个步骤: HA>OkA/  
    1. 创建Matlab服务器。 HC,Se.VYS  
    2. 移动探测面对于前一聚焦面的位置。 :6\qpex  
    3. 在探测面追迹光线 {{p7 3 'u  
    4. 在探测面计算照度 Jg| XH L)  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~R92cH>L  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 JFk lUgg  
    7. 用Matlab画出照度数据 !Q0w\j h  
    8. 在Matlab计算照度平均值 6,{$J  
    9. 返回数据到FRED中 k+pr \d~
