MatLab: Array Manipulating Functions

Major Reference Source: MatLab Verson 7.0

Since all types of data in MatLab are stored in the form of arrays, MatLab package provides some elementary array manipulating functions.

Elementary Array Manipulating Functions

Besides elementary arithmetic function and common mathematical functions, MatLab package also provides some basic array manipulating functions for manipulating matrices and arrays.

Array Creation and Concatenation Functions

Function	Description
accumarray(A,B)	to construct a new array by accumulating the elements of an array B according to the corresponding index specified by the array A in a row vector form with others are zeros.
blkdiag(A,B,...)	to construct a new matrix by placing the specified list of matrices, A,B,..., diagonally with others are zeros.
eye([A,B],C)	to construct a new matrix by placing one diagonally with others are zeros of dimension A-by-B and optional class C or a A-by-A identity matrix, If B is not specified.
false([A,B,..])	to construct a new false array by placing False or logical zeros of dimension according to the specified the list of dimension A-by-B-by-... or a A-by-A square matrix, If only one dimension A is specified. False by itself is short-hand for logical(0)
freqspace
linspace(a,b,n)	to construct a new linearly spaced row vector pf n points with value between and including a and b. The default number of points is 100 points If n is not specified.
logspace(a,b,n)	to construct a new logarithmically spaced row vector pf n points with value between and including decades 10^a and 10^b. The default number of points is 50 points If n is not specified. And if b is equal to pi, then the value of points becomes between and including 10^a and pi.

ones
rand
repmat
true([A,B,..])	to construct a new true array by placing True or logical ones of dimension according to the specified list of dimension A-by-B-by-... or a A-by-A square matrix, If only one dimension A is specified. True by itself is short-hand for logical(1)
