    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。 yb{{ z@  
    (&S[R{=^j  
    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: P,;b'-5C  
    enableservice('AutomationServer', true) 4B8Se  
    enableservice('AutomationServer') l9NOzAH3  
    a$zm/  
    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 {&}/p-S  
    '=,rb  
    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: $K.%un Gm  
    1. 在FRED脚本编辑界面找到参考. r>:L$_]L  
    2. 找到Matlab Automation Server Type Library .1}rzh}8  
    3. 将名字改为MLAPP R-A'v&=

    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'C:n<g

    现在将脚本代码公布如下,此脚本执行如下几个步骤: B==a  
    1. 创建Matlab服务器。 %V<F<  
    2. 移动探测面对于前一聚焦面的位置。 5}MlZp  
    3. 在探测面追迹光线 ^M(`/1:  
    4. 在探测面计算照度 o~o6S=4,}  
    5. 使用PutWorkspaceData发送照度数据到Matlab MX`Wg  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 mU3Y)  
    7. 用Matlab画出照度数据 2 ]DCF  
    8. 在Matlab计算照度平均值 &ap`}^8pM  
    9. 返回数据到FRED中 3:~l2KIP4
