Illustration of Input in a for loop:
In this illustration, the loop variable iv iterates through the values 1 through 3, therefore the action is repeated three times. The action holds of prompting the user for a number and echo printing it with one decimal place.
Rather than of simply echo-printing the numbers, it is frequently necessary to store them in a vector. The one way of accomplishing this is to begin by preallocating the vector and then putting the values in each element, as we saw in earlier example. Here is a function which does this, and returns the resulting vector. The function receives input argument n, and repeats the procedure n times.
Here is an illustration of calling this function and storing the resulting vector in a variable known as the myvec.
>> myvec = forinputvec(3)
Enter a number: 44
Enter a number: 2.3
Enter a number: 11
myvec =
44.0000 2.3000 11.0000
Mode The mode of a data set is the value which appears most often. The built-in function in a MATLAB for this is known as the mode. >> x = [9 10 10 9 8 7 3 10 9 8 5 10];
Example of Nested functions: For illustration, the function below computes and returns the volume of a cube. Three arguments are then passed to it, for the width and length of
Steps for input output functions - Lower level file: The steps involved are as shown below: Open the file. Read the file, write to the file, or append to the file.
Index vector: The index vector is then used as the indices for original vector. To get grades vector in ascending order, the indices used would be grades (2), grades (5), and
Illustration of Median When the vector is not in sorted order to start with, the median function will still return the right answer (it will sort the vector automatically). For
Working of Editor and debugger: Editor/Debugger, or commands can be typed from Command Window. For illustration, the dbstop command below will set a breakpoint in the fifth li
Statistics There are numerous statistical analyses which can be executed on data sets. In MATLAB software, the statistical functions are in the data analysis help topic known a
Generic code for Reading from Files: The generic code to complete this is as shown below: fid = fopen('filename'); if fid == -1 disp('File open not suc
Use of function polyval: The better the curve fit, the more exact these interpolated and extrapolated values will be. By using the subplot function, we can loop to display the
Nested Structures: The nested structure is a structure in which at least one of the members is itself a structure. For illustration, a structure for the line segment may co
