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.
Error-Checking for Integers: As MATLAB uses the type double by default for all the values, to check to make confirm that the user has entered an integer, the program have to c
Blanks function: The blanks function will generate a string consisting of n blank characters-that are kind of hard to see here! Though, in a MATLAB if the mouse is moved to hi
Strcat function - Concatenation : The strcat function, though, will eliminate the trailing blanks from strings before concatenating. Note that in these illustrations, the trail
Concatenation: The String concatenation means to join the strings altogether. Of course, as strings are merely vectors of the characters, the technique of concatenating vector
Program of built-in factorial function: Calling this function yields similar result as the built-in factorial function: >> fact(5) ans = 120 >> factorial(
Nested IF-ELSE statements: The if-else statement is used to select between the two statements. In order to select from more than two statements, the if-else statements can als
Functions to create special matrices: The MATLAB also has various functions which create special matrices. For illustration, the zeros function generates a matrix of all zeros
Find Minimum and Maximum for each row To find the maximum (or minimum) for each row, the dimension of 2 (that is how a MATLAB refers to rows) can be identified as the third arg
Illustration of Logical vectors: Calling the function appears to return similar vector as simply vec > 5, and summing the result still works to determine how many elements wer
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,
