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.
Counting in a While Loop: Whenever it is not known ahead of the time how many values will be entered into the script, it is often essential to count the number of values which
Give the formula for a rational function that has a hole at x=7 & vertical asmptote at x=-3/2
Print an imaginary number: To print an imaginary number, the function disp will show both parts automatically: >> disp(z1) 4.0000 + 2.0000i The function fprint
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
bar and barh functions: For a matrix, the bar and barh functions will group altogether the values in each and every row. The illustration is as shown: rm = randint(2,4,[1
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
Illustration of Variance For illustration, for the vector [4, 6, 1, 5], there are n = 4 values therefore n - 1 is 3. The mean of this data set is also 4. The variance will be
If I have a vector representing the packed storage form of a symmetric matrix, how do I perform a cholesky factorisation on that?
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
