This has no effect if A is already a matrix or vector. A(j:k) uses the vector j:k to index into A. If A is a vector, then A(j:k) has the same orientation as A. If A is a matrix, thenA(j:k) is a row vector.

A single row of data has spaces or commas in between the elements, and a semicolon separates the rows. For example, create a single row of four numeric elements. The size of the resulting matrix is 1-by-4 because it has one row and four columns. A matrix of this shape is often referred to as a row vector.

sz = size(A) returns a row vector whose elements are the lengths of the corresponding dimensions of A. For example, if A is a 3-by-4 matrix, then size(A) returns the vector [3 4] . If A is a table or timetable, then size(A) returns a two-element row vector consisting of the number of rows and the number of table variables.

2017年5月18日 · Mathematically, a vector is an element of a vector space. Sometimes, it's just an n-tuple $(a,b,c)$. In physics, one often demands that the tuple has certain transformation properties to be called a vector (as opposed to e.g. a pseudovector). Sometimes its not a tuple, but e.g. an element of a hilbert space.

To create an array with multiple elements in a single column, separate the elements with semicolons ';'. This type of array is called a column vector.

2015年2月25日 · yes, putting that symbol in there will turn a row vector into a column, and vice versa. This works for matrices too, effectively rotating them by 90 degrees. AnnaMaria Accardo on 25 Feb 2015

2013年11月6日 · It saves the time for transposing; It calculates the wanted sum over the rows also if A is a coulmn matrix. Then the output must equal the input, but with sum(A')' a scalar is replied, because Matlab decides smartly to sum over the column.

If A is a vector, then sum(A) returns the sum of the elements. If A is a matrix, then sum(A) returns a row vector containing the sum of each column. If A is a multidimensional array, then sum(A) operates along the first array dimension whose size does not …
