sprintf function:
The sprintf function works precisely like the fprintf function, but rather than printing it generates a string. Here are some illustrations in which the output is not suppressed and hence the value of the string variable is shown:
>> sent1 = sprintf('The value of pi is %.2f', pi)
sent1 =
The value of pi is 3.14
>> sent2 = sprintf('Some numbers: %5d, %2d', 33, 6)
sent2 =
Some numbers: 33, 6
>> length(sent2)
ans =
23
In the illustration below, on the other hand, the outcome of the assignment is suppressed; therefore the string is generated including an arbitrary integer and stored in the string variable. Then, few exclamation points are concatenated to that string.
>> phrase = sprintf('A random integer is %d', . . .
randint(1,1,[5,10]));
>> strcat(phrase, '!!!')
A random integer is 7!!!
All the conversion specifiers which can be used in the fprintf function can also be used in the sprintf function.
Strings as matrix: The matrix can be generated, that consists of strings in each row. Therefore, essentially it is created as a column vector of strings, but the final result
Built-in functions for Complex numbers: We know that in MATLAB both i and j are built-in functions which return √-1 (therefore, they can be thought of as built-in constants).
Common form of the switch statement: The common form of the switch statement is as shown below: switch switch_expression case caseexp1 action1 case cas
Use of string variables: The Characters involve letters of the alphabet, punctuation marks, digits, white space, and control characters. The Control characters are characters
Writing variables to a File: The save command is used to write variables to a file, or to append the variables to a MAT-file. By the default, save function writes to a MAT-fil
Indexed empty matrix: The Individual elements cannot be eliminated from matrices, as matrices always have the similar number of elements in every row. >> mat = [7 9 8; 4 6
fprintf function - File function: The fprintf function really returns the number of bytes which was written to the file, therefore if you do not want to see that number, suppr
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
Complex numbers: A complex number is commonly written in the form z = a + bi here a is known as the real part of the number z, b be the imaginary part of z, and i is √-1
Matrix of Plots: The other function which is very useful with any type of plot is subplot that creates a matrix of plots in the present Figure Window. The three arguments are
