    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。 N$!aP/b  
    A^2n i=b  
    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: VRb+-T7"  
    enableservice('AutomationServer', true)  46^9O 5J  
    enableservice('AutomationServer') 8[k:FGp>  
     &x":  
    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 Lhts4D/V7  
    @QN(ouqQ  
    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: /wR,P  
    1. 在FRED脚本编辑界面找到参考. hf JeVT-/v  
    2. 找到Matlab Automation Server Type Library ~6Xr^An/Z  
    3. 将名字改为MLAPP D2y[?RG  
    K9HXy*y49  
    n@JZ2K4  
    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)aWTI

    现在将脚本代码公布如下,此脚本执行如下几个步骤: fi,h`mdT?  
    1. 创建Matlab服务器。 N|rB~  
    2. 移动探测面对于前一聚焦面的位置。 1_jd1 UT  
    3. 在探测面追迹光线 vG{lxPIj  
    4. 在探测面计算照度 SSAf<44e  
    5. 使用PutWorkspaceData发送照度数据到Matlab x+;a2yE~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 .eHOG]H  
    7. 用Matlab画出照度数据  z@8W  
    8. 在Matlab计算照度平均值 sQXj?5!  
    9. 返回数据到FRED中 <2V:tj)?P
