    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。 tAte)/0C  
    y+6o{`0  
    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: S.q].a  
    enableservice('AutomationServer', true) dW~*e2nq  
    enableservice('AutomationServer') WRDjh7~Efn  
    meks RcF  
    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 -'BA{#e}L  
     S"$m]  
    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: u[/m|z  
    1. 在FRED脚本编辑界面找到参考. Yf~{I-|`q  
    2. 找到Matlab Automation Server Type Library .?e\I`Kk^'  
    3. 将名字改为MLAPP lBFMwJU)

    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。 oK%K}{`

    3. 在探测面追迹光线 jSuL5|Gui  
    4. 在探测面计算照度 JPWOPB'H  
    5. 使用PutWorkspaceData发送照度数据到Matlab X'% ;B  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 B0!"A  
    7. 用Matlab画出照度数据 ;~u{56  
    8. 在Matlab计算照度平均值 -7&Gi +]  
    9. 返回数据到FRED中 vp crPVA^
