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.
ischar function: The ischar function return the logical true if an array is a character array, or logical false if not. >> vec = 'EK127'; >> ischar(vec) ans =
Example of Interpolation and extrapolation: The MATLAB has a function to do this, known as polyfit. The function polyfit finds the coefficients of the polynomial of the partic
Displaying expressions: The good-looking function will show such expressions by using exponents; for illustration, >> b = sym('x^2') b = x^2 >> pretty(b)
Indexing into Vectors of structures: Frequently, when the data structure is a vector of structures, it is essential to iterate through the vector in order by various fields. F
Function call: In the function call, not any arguments are passed so there are no input arguments in the function header. The function returns an output argument, therefore th
readlenwid function: function call: [length, width] = readlenwid; function header: function [l,w] = readlenwid In the function call, not any argument is passed; henc

Example of image processing: The other illustration generates a 5 × 5 matrix of arbitrary integers in the range from 1 to the number of colors; the resultant image is as shown
Executing a program: Running the program would be completed by typing the name of the script; this would call the other functions: >> calcandprintarea Whenever prompt
Scaling: change a row by multiplying it by a non-zero scalar sri → ri For illustration, for the matrix:
