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];
Functions which return Values versus printing: Also, the function which computes and returns values (throughout the output arguments) does not generally print them; that is le
Function Stubs: The other common debugging method, which is used when there is a script main program which calls many functions, is to use the function stubs. A function stub
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
Example of sorting strings: To sort a cell array of strings, also the sort function is used. The illustration is as follows, >> engcellnames = {'Chemical','Mechanical',.
Areacirc function: The areacirc function can be called from the Command Window as shown here, or from a script. Here is a script which will prompt the user for the radius of o
Persistent Variables: Generally, whenever a function stops executing, then the local variables from that function are cleared. That means that each and every time a function i
Lower Level File I/O Functions: Whenever reading from data file, as long as the data in the file is "regular" the load function works-in another words, the similar type of dat
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
Core Objects: The Core Objects in MATLAB are the very fundamental graphics primitives. The description can be found under the MATLAB Help: Under the Contents tab, click the Ha
