    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。 @4pN4v8U  
    DIY WFVh  
    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: dFlx6H+R!0  
    enableservice('AutomationServer', true) P7 n~Ui~U  
    enableservice('AutomationServer') iiu\_ a=0b  
    Q["}U7j  
    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 ^t"\PpmK<d  
    L(L;z'3y  
    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: +J2=\YO  
    1. 在FRED脚本编辑界面找到参考. kciH  
    2. 找到Matlab Automation Server Type Library I'";  
    3. 将名字改为MLAPP .._wTOSq

    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。 +#O?sI#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: P _9O8"W  
    1. 创建Matlab服务器。 ^vzNs>eJ  
    2. 移动探测面对于前一聚焦面的位置。 qhogcAvE  
    3. 在探测面追迹光线 (g 8K?Q  
    4. 在探测面计算照度 9%x[z%06  
    5. 使用PutWorkspaceData发送照度数据到Matlab XG0,@Ly  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {d) +a$qj  
    7. 用Matlab画出照度数据 x ` $4  
    8. 在Matlab计算照度平均值 E 0YXgQa  
    9. 返回数据到FRED中 >y1/*)O9~
