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。 4A o{M O5MDGg 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:
,%8$D-4#_ enableservice('AutomationServer', true) :uvc\|:s enableservice('AutomationServer') `.8-cz
..$>7y} 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。 8MQbLj'H MBO,\t. 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: T{HfP 1. 在FRED脚本编辑界面找到参考. Iaa|qJ4 2. 找到Matlab Automation Server Type Library <G9<"{ 3. 将名字改为MLAPP m5qCq9Y .EzSSU7n) sL
