Jul 8, 2010 · Matrix and Array Operations MATLAB allows you to process all of the values in a matrix using a single arithmetic operator or function.

This example shows basic techniques and functions for working with matrices in the MATLAB® language. First, let's create a simple vector with 9 elements called a.

A matrix is a two-dimensional, rectangular array of data elements arranged in rows and columns. The elements can be numbers, logical values (true or false), dates and times, strings, categorical values, or some other MATLAB data type.

Matrices and arrays are the fundamental representation of information and data in MATLAB ®. You can create common arrays and grids, combine existing arrays, manipulate an array's shape and content, and use indexing to access array elements.

Jan 1, 2018 · In MATLAB®, there are three primary approaches to accessing array elements based on their location (index) in the array. These approaches are indexing by position, linear indexing, and logical indexing. You can also use mixed indexing by combining both positional and logical indexing.

This example shows basic techniques for creating arrays and matrices using MATLAB. Matrices and arrays are the fundamental representation of information and data in MATLAB.

inv performs an LU decomposition of the input matrix (or an LDL decomposition if the input matrix is Hermitian). It then uses the results to form a linear system whose solution is the matrix inverse inv(X).

Compute C by first finding the eigenvalues D and eigenvectors V of the matrix B.

You can create a multidimensional array by creating a 2-D matrix first, and then extending it. For example, first define a 3-by-3 matrix as the first page in a 3-D array.

Feb 12, 2013 · The best answer to your question will likely depend on what you want to do with A. Sometimes, I find the following commands useful, which will create an anonymous function, A, that takes two inputs, x1 and x2 and returns the matrix you describe.
