2022年3月4日 · 前面给大家介绍了☞ 【R语言】rep函数的使用，今天我们来举几个数据分析中的应用，例如差异表达分析时，样本类型变量，我们就可以使用rep函数来生成。

For the decimal implementation we would choose 10, for binary choose 2, and so on. The solution is to use functors, a feature of the SML module system that makes it easy to define such a parametric module. Rather than give the general syntax and semantics of functors in full detail, we will work out an example and use it to introduce the main ideas.

Make tuples and lists using built-in types and themselves. Note: 1-tuples don't exist in Standard ML. Operators have different priority levels. Higher priority operations are performed before lower priority operations. The operators *, +, and - work on both int and real types.

What is the difference between original SML and SML2? There are few design differences. - SML is more feature reach and more complete - SML2 is compile-time first - dependencies are not injected directly to guards/actions.

In SML (not just the REPL), this is also valid syntax. For some expressions exp1 : t1, exp2 : t2, we have that exp1;exp2 : t2 where exp1 is evaluated first, and then exp2 is evaluated thereafter. One thing to note is that in SML, only the value of the second expression is returned, and the type of the whole expression is the type of the last ...

I want to write a function in SML/NJ which will take 2 matrices as an arguments and it will multiply them. I can only use: function dot, which take 2 vectors and calculate scalar product:

2023年6月20日 · REP Fitness has been doing a complete redesign of their power racks and the REP SR-4000 Squat Rack is exactly that. Based on REP’s best-selling rack, the 4000 Series Squat Rack improves in nearly every area and is by far the sturdiest squat stand we’ve tested.

The Array2 structure provides polymorphic mutable 2-dimensional arrays. As with 1-dimensional arrays, these arrays have the equality property that two arrays are equal if they are the same array, i.e. , created by the same call to a primitive array constructor such as array , fromList , etc.; otherwise they are not equal.
