Strings as Vectors:
The Strings are considered as vectors of characters-or in another words, a vector in which each and every element is a single character-so numerous vector operations can be performed. For illustration, the number of characters in a string can be found by using the length function:
>> length('cat')
ans =
3
>> length(' ')
1
>> length('')
0
Notice that there is a distinction between an empty string, that has a length of zero, and a string consisting of a blank space, that has a length of one.
The Expressions can refer to a separate element, or a subset of a string or a transpose of the string:
>> mystr = 'Hi';
>> mystr(1)
H
>> mystr'
i
>> sent = 'Hello there';
>> length(sent)
11
>> sent(4:8)
lo th
Note that the blank space in the string is a valid character contained by the string.
Illustration of Empty vectors: The Empty vectors can also be used to delete elements from the arrays. For illustration, to remove the third element from array, an empty vector
Recursive Functions: The Recursion occurs whenever something is defined in terms of itself. In the programming, a recursive function is a function which calls itself. The Recu
strvcat function - concatenation: The function strvcat will concatenate it vertically, that means that it will generate a column vector of the strings. >> strvcat(fir
Refer the subset of a matrix: It is also possible to refer to the subset of a matrix. For illustration, this refers to the first & second rows, second & third columns: >> m
Changing Dimensions: In addition to transpose operator, the MATLAB has some built-in functions which change the dimensions or configuration of matrices, involving fliplr, resh
Illustration of Writing variables to a file: For illustration, in the below session in the Command Window, 3 variables are generated; these are then exhibited using who. Then,
Differentiation: The derivative of a function y = f(x) can be written as follows or f '(x) and is defined as the rate of change of the dependent variable y with respe
The variance is generally defined in terms of the arithmetic mean as: At times, though, the denominator is defined as n instead of n - 1. The default definition used by t
Empty Vectors: An empty vector or in another words, a vector which stores no values, can be generated using the empty square brackets: >> evec = [] evec = [] >> lengt
User-defined functions: Therefore, although many functions compute and return values, some do not. A few functions rather merely accomplish a task. Regardless of what type of
