Logical Built-In Functions:
There are built-in functions in the MATLAB which are useful in conjunction with vectors or matrices of all logical true or false values; two of these are the functions 'any' and 'all'. The function 'any' returns a logical true when any element in a vector is logically true, and false if not. The function 'all' returns a logical true only when all elements are logically true. Here are some illustrations. For the variable vec1, all the elements are logical true therefore both any and all return true.
>> vec1 = [1 3 1 1 2];
>> any(vec1)
ans =
1
>> all(vec1)
For vec2, various elements are logical true so 'any' returns the true but 'all' returns false.
>> vec2 = [1 1 0 1]
vec2 =
1 1 0 1
>> any(vec2)
>> all(vec2)
0
Illustration of Indexing into vectors of structures: For illustration, the function to print the information from packages has been modified therefore in addition to the vecto
Example of Median For the vector [1 4 5 9 12 33], the median is the average of the 5 & 9 in the middle: >> median([1 4 5 9 12 33]) ans = 7
Program of Persistent variables: The program below elaborates this. The script calls a function func1 that initializes a variable count to 0, then increment it, and print the
Execution of persistent variables: The functions can also be called from the script or from the Command Window, as shown here. For illustration, the functions are called first
Example of Core objects: The one core graphics object is a line that is also what the plot function produces. Here is an illustration of generating a line object, altering som
Debugging Techniques: Any error in the computer program is called a bug. This word is thought to date back to the 1940s, whenever a problem with an early computer was found to
Advanced File Input and output: Where 'format' involves the conversion characters much like those used in the fprintf function. For illustration, to read the file 'subjexp.dat
bjjh
Illustrations of Sequential search: The two illustrations of calling such function is as shown below: >> values = [85 70 100 95 80 91]; >> key = 95; >> seqsearch
Advanced File Input and Output: In that section, we saw how to read the values entered by user using the input as well as the output functions disp and fprintf, that shows inf
