在vce的物理里面, vector这个概念会经常被提及,而且往往问题的答案就是一个vector。所以同学们不仅要知道vector这个概念,还需要学会如何拆分和合成vector来进行运算。 那么首先vector和scalar在中文里面的意思: Vector—矢量或者向量 Scalar—标量 (这里的中文意思只是为了方便同学们去理解vector和scalar的含义,是并不需要同...

A scalar value is a quantity with only one component, its magnitude (a numerical value). A vector is a quantity with two components: magnitude and direction. Scalar vs Vector example Examples of scalars and vectors: Scalar Vector 39 degrees Celsius (temperature) N/A 5m/s (speed) 5 m/s ...

Vector-scalar real arithmetic functions Perform element-wise operations on combinations of vectors of real values and scalar values. Overview The vDSP library provides a suite of general-purpose, high-performance arithmetic functions that are alternatives toforloops andmapwhen you apply operations on col...

If you also had its width and depth, you could find another scalar value for the building, its volume. When a measure of magnitude is accompanied by a directional element, it becomes a vector, which is defined as the magnitude and direction of something, as with velocity or displacement. ...

For example, the vector scale operation multiplies each component of a vector by the same scalar, a*X=a*x1, a*x2, . . . , a*xn There are also monadic reduction operators, for example, adding all of the elements in a vector, finding the element of the greatest absolute value, or ...
