Question

我有一个matlab文件，我不能在这里发布（3000行），其中包含许多从GUI中使用的函数。

我正在使用包含3000行的matlab文件，这些行具有如此多的设计GUI功能

当我使用Function A时，该函数与使用其他几个函数相关，并使其成为循环，通过花费很长时间运行很多次function A (1600-2000)次迭代。

当我达到400-500时，Matlab给了我

error : "Error while evaluation UIcontrol callback"

我必须杀死现有进程，然后退出Matlab并从上一次迭代中再次运行，这会产生错误。所以我的问题不是基于函数调用，而是基于内存或可能是临时内存。

是否可以通过Matlab增加临时内存使用量？

我最多会增加首选项“Java热记忆”，但这种偏好不会改变我的问题。

有没有办法解决这个问题？
