    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。 FLY Ca  
    +}a ]GTBgA  
    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: ? C/Te)  
    enableservice('AutomationServer', true) }-@`9(o`)  
        enableservice('AutomationServer') xL" |)A =  
    +[tP_%/r'^  
    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 \W`w` o

    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/-63O_  
    1. 在FRED脚本编辑界面找到参考. l\n@cQR  
    2. 找到Matlab Automation Server Type Library `Ry]y"K  
        3. 将名字改为MLAPP k]I0o)+O.

    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。 & :7ZQ1

    1. 创建Matlab服务器。 rX1QMR7?  
    2. 移动探测面对于前一聚焦面的位置。 YSe.t_K2C

    4. 在探测面计算照度 to$h2#i_  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?pza G{  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Y(d$  
    7. 用Matlab画出照度数据 pt}X>ph{
