    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。 d[qEP6B  
    8/kx3  
    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: } (O D<  
    enableservice('AutomationServer', true) J_((o  
    enableservice('AutomationServer') !Barc ,kA  
    Y~\`0?ST  
    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 vb80J<4  
    o 0cc+  
    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: E?;T:7.%  
    1. 在FRED脚本编辑界面找到参考. G Yy!`E  
    2. 找到Matlab Automation Server Type Library .,BD DPFB  
    3. 将名字改为MLAPP Xk$l-Zfse

    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。 ?AM 8*w

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ^QL/m\zq@%  
    1. 创建Matlab服务器。 Yqz[sz5+m

    3. 在探测面追迹光线 fuIv,lDA  
    4. 在探测面计算照度 e8ig[:B>+  
    5. 使用PutWorkspaceData发送照度数据到Matlab # |*,zIYo  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 f 7QUZb\
