    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。 ;[~^( . f  
    BWEv1' v  
    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: V6+Zh>'S  
    enableservice('AutomationServer', true) A^g>fv  
    enableservice('AutomationServer') " $=qGHA~  
    0n5!B..m}  
    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 z8tl0gd%D

    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: 2 `&<bt[g  
    1. 在FRED脚本编辑界面找到参考. CWvlr nv  
    2. 找到Matlab Automation Server Type Library R&!]Rl9hf  
    3. 将名字改为MLAPP UoRDeYQ`E

    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。 8KKz5\kn7

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~o Fh>9u  
    1. 创建Matlab服务器。 H9E(\)@  
    2. 移动探测面对于前一聚焦面的位置。 `sxN!Jj?  
    3. 在探测面追迹光线 @<5Tba>SC  
    4. 在探测面计算照度 j"6:A  
    5. 使用PutWorkspaceData发送照度数据到Matlab X~zRZ0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w&C1=v -h  
    7. 用Matlab画出照度数据 EW9b*r7./  
    8. 在Matlab计算照度平均值 ,`"K  
    9. 返回数据到FRED中 SS0_P jKz
