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.
Built-in function for Differentiation: The MATLAB has a built-in function, diff that returns the differences between consecutive elements in a vector. For illustration, >>
Example of Symbolic Expression When there is more than one variable, the MATLAB selects which to solve for. In the illustration below, the equation ax 2 + bx = 0 is solved. Th
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
Plot types: Besides plot and bar, there are another plot types like stem plots, histograms, stem plots, area plots and pie charts, and also other functions which customize the
Example of Logical built-in functions: For equivalent to all the function, we should make sure that the entire elements in the vector are logically true. The one way of doing
