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.

The code generator does not specialize multiplication by pure imaginary numbers—it does not eliminate calculations with the zero real part. For example, (Inf + 1i)*1i = (Inf*0 – 1*1) + (Inf*1 + …

MATLAB ® stores matrix data and arrays (1–D, 2–D, ...) in column-major format as a vector. Simulink ® and the code generator can store array data in column-major or row-major format. …

Compute the mean values of the matrix, excluding missing values. For matrix columns that contain any NaN value, mean computes with the non-NaN elements. For matrix columns that …

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 …

Compute the standard deviation of the matrix, excluding missing values. For matrix columns that contain any NaN value, std computes with the non-NaN elements. For columns in A that …

This MATLAB function returns a square diagonal matrix with the elements of vector v on the main diagonal.

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 …

If you define one or both of the operands as variable-size matrices at code generation time, the code generator produces code for matrix-matrix multiplication. If one of these operands is a …
