    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。 ;Qt/(/  
    fP4P'eI  
    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: T`]%$$1s  
    enableservice('AutomationServer', true) \l3z <\  
        enableservice('AutomationServer') WO%pX+PoH  
    {#?|&n<  
    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 0 !%G #~th  
    [75?cQD  
    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: A*+gWn,4Y_  
    1. 在FRED脚本编辑界面找到参考. kGnT4R*E  
    2. 找到Matlab Automation Server Type Library kzCJs  
        3. 将名字改为MLAPP ,!^c`_Q\>@  
         5 Slz ^@n  
         @ls/3`E/5E  
    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。 @IbZci)1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: j`@`M*)GB  
    1. 创建Matlab服务器。 <uFj5.  
    2. 移动探测面对于前一聚焦面的位置。 _0^>^he  
    3. 在探测面追迹光线 *rxYal4ad  
    4. 在探测面计算照度 Z VdQ$  
    5. 使用PutWorkspaceData发送照度数据到Matlab J{a9pr6  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 j7w9H/XF}  
    7. 用Matlab画出照度数据 G,<d;:  
    8. 在Matlab计算照度平均值 _(:$ :*@  
    9. 返回数据到FRED中 Zz:%KUl3
