    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。 9tsI1]1[m  
    \y^Od7F  
    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: `,d*>  
    enableservice('AutomationServer', true) Ql a'vcT  
        enableservice('AutomationServer') QlJ cj+_h  
    A,i.1U"w8  
    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 ~C=I{qzF+  
    *T j(IN  
    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: Htn=h~U`z  
    1. 在FRED脚本编辑界面找到参考. |t*(]U2O0  
    2. 找到Matlab Automation Server Type Library m\`dLrPX4j  
        3. 将名字改为MLAPP <uUQ-]QOIh

    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。 K[0.4+

    3. 在探测面追迹光线 |m7U^  
    4. 在探测面计算照度 `Bk7W]{L
