What are the "scalar fields" and "composite fields" in JAVA?
Jul 11, 2019 · The terms 'scalar type' or 'scalar field' are usually used to contrast them with compound types/fields. A compound type is easiest to define and it is a type that contains multiple distinct elements. These elements can have the same type, in which case the compound is an array or a list, or different types, in which case the compound is ...
What is meant by a primitive data type?
Mar 15, 2012 · For example, in languages like C and C++, you have a number of built-in scalar types - int, float, double, char, etc. These are "primitive" in the sense that they cannot be decomposed into simpler components. From these basic types you can define new types - pointer types, array types, struct types, union types, etc.
Variables (scalars and matrices) assignment in Python
Jul 8, 2010 · Noted. Since the scalar is created using python, it is not behaving similar to array/matrix created by Numpy. I understand that: If we have to initialize 5 matrices, it is better to initialize separately. This way they are representing separate links to 5 separate matrices. –
performance - Why does expressing calculations as matrix ...
Using SIMD instructions (confusingly, this is also called "vectorization" but in a different sense than in the text quotes in the question). In essence, instead of 4 or 8 or so scalar arithmetic instructions, give the CPU one instruction that performs arithmetic on 4 or 8 or so registers in parallel. This can literally make some calculations ...

Paradigm for handling list of things or single elements
Sep 5, 2017 · @KilianFoth: I don't think this applies here. "Composite design pattern" would require to wrap the passed parameter in an additional class hierarchy, but additional wrappers is exactly what the OP tries to avoid. Moreover, in Python one can already use a list or a scalar in exchange when calling a function, that is syntactically ok. –
What's faster.. Multiple variables or single array?
The compiler may apply scalar replacement of aggregates (SRA, SRoA), which means the local array (which is used in elementwise single assignment way) approach and the local variables approach might be optimized in the same way, without requiring a stack space for hundreds of float elements or variables.
Why Protobuf 3 made all fields on the messages optional?
