Logical scalar values:
The MATLAB also has or and and operators which work element wise for the matrices:
These operators will compare any of the two vectors or matrices, as long as they are of similar size, element-by-element, and return a vector or matrix of similar size of logical 1's and 0's. The operators | | and && are only used with scalars, not matrices. For illustration,
>> v1 = [3 0 5 1];
>> v2 = [0 0 2 0];
>> v1 & v2
ans =
0 0 1 0
>> v1 | v2
1 0 1 1
>> v1 && v2
??? Operands to the || and && operators should be convertible to the logical scalar values.
As with numerical operators, it is significant to know that the operator precedence rules. Table shows the rules for the operators which have been covered faraway, in the order of the precedence.
Subfunctions: Though, it is possible to have more than one function in a given M-file. For illustration, if one function calls the other, the first function would be the prima
Changing Case: The MATLAB has two functions which convert strings to all uppercase letters, or all lowercase, known as the upper and lower. >> mystring = 'AbCDEfgh';
Displaying expressions: The good-looking function will show such expressions by using exponents; for illustration, >> b = sym('x^2') b = x^2 >> pretty(b)
Illustration of Preallocating a Vector: Illustration of calling the function: >> myveccumsum([5 9 4]) ans = 5 14 18 At the first time in the loop, outvec wil
Illustration of Variable scope: Running this function does not add any of variables to the workspace, as elaborated: >> clear >> who >> disp(mysum([5 9 1]))
Illustration sorting vectors of structures: This function sorts the structures depend only on the price field. A more common function is shown next, that receives a string whi
Matrix definitions: As we know the matrix can be thought of as a table of values in which there are both rows and columns. The most common form of a matrix A (that is sometime

Function used in binary search: The function below implements this binary search algorithm. It receives two arguments: the sorted vector and a key (on the other hand, the func
IS Functions for Strings: There are many functions for strings, that return logical true or false. The function isletter returns the logical true when the character is a lette
