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
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',.
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
Opening and Closing a File: The Files are opened with the fopen function. By the default, fopen function opens a file for reading. If the other mode is preferred, a permission
Rectangle - graphics objects: The other core graphics object is the rectangle that can have curvature added to it (!!). Merely calling the function rectangle without any argum
Need of a nested loop: How would we sum each individual column, rather than getting an overall sum? Answer: The programming technique would need a nested loop in whi
Indexing: The Indexing is an alternate to sort a vector. With indexing, the vector is left in its original order. An index vector is used to point values in the original vecto
Polynomials: Simple curves are polynomials of various degrees, or orders. The degree is the integer of the highest exponent in the expression. The illustrations are as follows
Types of errors: There are some various kinds of errors which can occur in a program, that fall into the categories of run-time errors, syntax errors, and logical errors. T
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 customizing plots: As the other illustration of customizing plots, the pieces of a pie chart can be "exploded" from the rest. In this situation, the two vectors are
