## How do you do a Cartesian product in Matlab?

X = CARTPROD(A,B,C,…) returns the cartesian product of the sets A,B,C, etc, where A,B,C, are numerical vectors. This function requires IND2SUBVECT, also available (I hope) on the MathWorks File Exchange site.

**What is the formula for Cartesian product?**

The Cartesian square of a set X is the Cartesian product X2 = X × X. An example is the 2-dimensional plane R2 = R × R where R is the set of real numbers: R2 is the set of all points (x,y) where x and y are real numbers (see the Cartesian coordinate system).

**What is the product of Cartesian product?**

In mathematics, the Cartesian Product of sets A and B is defined as the set of all ordered pairs (x, y) such that x belongs to A and y belongs to B. For example, if A = {1, 2} and B = {3, 4, 5}, then the Cartesian Product of A and B is {(1, 3), (1, 4), (1, 5), (2, 3), (2, 4), (2, 5)}.

### How do you find the product in Matlab?

B = prod( A ) returns the product of the array elements of A .

- If A is a vector, then prod(A) returns the product of the elements.
- If A is a nonempty matrix, then prod(A) treats the columns of A as vectors and returns a row vector of the products of each column.
- If A is an empty 0-by-0 matrix, prod(A) returns 1 .

**What is the Cartesian product of A ={ 1 2 and B ={ a B?**

Hence A×B={(1,a),(1,b),(2,a),(2,b)} Was this answer helpful?

## What is the difference between Ndgrid and Meshgrid?

Summary: NDGRID is to be used for higher dimensionality use and for when you want the results to reflect matrix/array notation: MESHGRID is to be used for visualizing data and should be used primarily for when plotting two or three dimensional data.
