You can use funm with appropriate second arguments to find matrix exponential, logarithm, and square root. However, the more efficient approach is to use the functions expm, logm, and sqrtm for this task.

This example shows basic techniques and functions for working with matrices in the MATLAB® language.

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

To determine if an array is empty, a scalar, or a matrix, use the functions isempty, isscalar, and ismatrix. You can also determine the orientation of a vector with the isrow and iscolumn functions.

MATLAB has many functions that help create matrices with certain values or a particular structure. For example, the zeros and ones functions create matrices of all zeros or all ones.

Create a matrix and compute the standard deviation of each column according to a weight vector w.

Create a matrix and compute the weighted mean of the matrix according to a weighting scheme specified by W. The mean function applies the weighting scheme to each column in A.

Create a matrix A and compute the largest elements in each column, as well as the row indices of A in which they appear.

This MATLAB function returns a vector containing the linear indices of each nonzero element in array X.

This MATLAB function evaluates the user-defined function fun at the square matrix argument A.
