Math.mqh 文件应该放在 terminal_data_folder\MQL5\Include\Math\Stat\ 文件夹中。它无法在MT4下编译。#property strict does not help

这是一个不支持 MQL4 的 MQL5 库。
该矩阵库不需要类。
这是一个 MQL5 库,不支持 MQL4。
但它在 MQL4 中 99% 有效,就像 GraphPlot 一样。如果他们修复了 MQL4 中的错误--所有重载都不能应用于函数调用,那么它就能 100% 工作。
我仔细查看过,但这不是 MQL4 的错误,而是 MQL5 的错误!

MQL4 可以正确地骂人--没有一个重载可以应用到 函数调用中。@Renat Fatkhullin,错误?
MQL4 正确地发出了警告--没有一个重载可以应用于 函数调用。而 MQL5 则在出现明显错误时保持沉默。
这不是错误。MQL5 有这些函数。
这不是错误。MQL5 具有这些功能。
您好,
,在 R 中计算伽马分布的量值时遇到了一个问题
:
> qgamma(0.05,2,scale=1)
[1] 0.3553615
> qgamma(0.05,10,scale=1)
[1] 5.425406
,在 mql5 中:
结果:
0.3553615106986621
错误 4
build 1596
你好,
在计算伽马分布的量值时遇到了一个问题
下午好,感谢您的留言。
错误 4 意味着牛顿反向迭代算法中的收敛问题,该算法用于查找量值。我们将对此进行研究。
