What does Union do in Matlab?
Description. C = union( A,B ) returns the combined data from A and B with no repetitions. C is in sorted order. If A and B are tables or timetables, then union returns the combined set of rows from both tables.
How do you combine two sets in Matlab?
For example, to merge two sets of data into a two-dimensional array, use the semicolon operator as in the following line: array2d = [set1; set2]; Sorting this array will have the same result as sorting the sets separately before concatenating them.

What is the union of two vectors?
The union of vectors return all the unique values in both the vectors. For example, if we have a vector x that contains 1, 2, 3, 4, 2, 3, 4, 1, 1, 4 and another vector that contains 2, 1, 2, 4, 5, 7, 5, 1, 2, 3, 7, 6, 5, 7, 4, 2, 4, 1, 5, 8, 1, 3 then the union of these two vectors will be 1, 2, 3, 4, 5, 6, 7, 8.
How do I combine two arrays in Matlab?
C = cat( dim , A1,A2,…,An ) concatenates A1 , A2 , … , An along dimension dim . You can use the square bracket operator [] to concatenate. For example, [A,B] or [A B] concatenates arrays A and B horizontally, and [A; B] concatenates them vertically.
What is a flag in MATLAB?
Introduction to Matlab Flag. Flag is a variable that we use as an indication or a signal to inform our program that a specific condition is met; mostly it is a Boolean variable (taking two values: True or False).
What is Varargin MATLAB?
varargin is an input variable in a function definition statement that enables the function to accept any number of input arguments. Specify varargin by using lowercase characters. After any explicitly declared inputs, include varargin as the last input argument .
How do you join tables in Matlab?
Merge Tables by Specifying One Key Variable
Create a new table, T , containing data from tables Tleft and Tright . Use Var2 in tables Tleft and Tright as the key variable to the join function. join adds a unique suffix to the nonkey variable, Var1 , to distinguish the data from tables Tleft and Tright .

MATLAB – Set Operations – Tutorialspoint
MATLAB – Set Operations, MATLAB provides various functions for set operations, like union, intersection and testing for set membership, etc.
What is the difference of union and intersection?
The union of two sets contains all the elements contained in either set (or both sets). The union is notated A ⋃ B. The intersection of two sets contains only the elements that are in both sets.
What is union in linear algebra?
Classic linear algebra exercise: the union of a subspace is a subspace if and only if one is contained in the other. This is also good practice with the definition of a subspace, and also shows how to prove statements of the form p implies (q or r) Check out my vector space playlist: list…
How do you concatenate an array?
In order to combine (concatenate) two arrays, we find its length stored in aLen and bLen respectively. Then, we create a new integer array result with length aLen + bLen . Now, in order to combine both, we copy each element in both arrays to result by using arraycopy() function.
How do I combine two rows in MATLAB?
To arrange A and B as two rows of a matrix, use the semicolon. To concatenate two matrices, they must have compatible sizes. In other words, when you concatenate matrices horizontally, they must have the same number of rows. When you concatenate them vertically, they must have the same number of columns.
How do you append to an array in MATLAB?
- For an existing vector x, you can assign a new element to the end using direct indexing. For example. Theme. …
- or. Theme. x(end+1) = 4;
- Another way to add an element to a row vector “x” is by using concatenation: Theme. x = [x newval]
- or. Theme. x = [x, newval]
- For a column vector: Theme.

What’s the difference between & and && in Matlab?
& is a logical elementwise operator, while && is a logical short-circuiting operator (which can only operate on scalars).
What is the function of the flag?
Flags originally were used mainly in warfare, and to some extent they have remained insignia of leadership, serving for the identification of friend or foe and as rallying points. They are now also extensively employed for signaling, for decoration, and for display.
At what will Matlab look first for a called function?
MATLAB searches the path for the given function name, starting at the first directory in the path string and continuing until either the function file is found or the list of directories is exhausted.
What is Varargin Nargin?
nargin( fun ) returns the number of input arguments that appear in the fun function definition. If the function includes varargin in its definition, then nargin returns the negative of the number of inputs.
What is Varargout in MATLAB?
varargout is an output variable in a function definition statement that enables the function to return any number of output arguments. Specify varargout using lowercase characters, and include it as the last output argument after any explicitly declared outputs.
In which case would you use Varargin in a function?
- varargin is used when the number of input parameter might change. Basically, it puts all input arguments into a cell array. The number of input parameters is given by.
- You can access any of the input values inside the function by.
- where ind is the index number of your argument.
How do you combine text in Matlab?
Description. newStr = join( str ) combines the text in str by joining consecutive elements of the input array, placing a space character between them. str can be a string array or a cell array of character vectors. newStr has the same data type as str .
What is outer join in SQL?
When performing an inner join, rows from either table that are unmatched in the other table are not returned. In an outer join, unmatched rows in one or both tables can be returned. There are a few types of outer joins: LEFT JOIN returns only unmatched rows from the left table.
What is left join SQL?
The LEFT JOIN command returns all rows from the left table, and the matching rows from the right table. The result is NULL from the right side, if there is no match.
How do you check if a number is odd in MATLAB?
To determine whether a number n is even or odd you can use the function rem(n,2). If rem(n,2) equals 0 then the number is even, otherwise it is odd. One nice thing about Matlab is that your program will work fine, no matter how inefficient you wrote it.
How do you find the intersection of two matrices?
For finding the intersection of both matrix simply iterate over their size and print * if element at particular position in both matrix are not equal else print the element.

How do you show variables in MATLAB?
Command Window — To view the value of a variable in the Command Window, type the variable name. For the example, to see the value of a variable n , type n and press Enter. The Command Window displays the variable name and its value. To view all the variables in the current workspace, call the who function.
