MDP Toolbox for MATLAB

mdp_check_square_stochastic

Checks whether a matrix is square and stochastic.

Syntax

error_msg = mdp_check_square_stochastic (T)

Description

mdp_check_square_stochastic checks if the matrix (T) is square and stochastic (sums of rows equal to 1).
If it is the case, the function returns an empty error message. In the opposite case, the function returns an error message describing the problem.

Arguments

• T : a matrix.

Evaluation

• error_msg : error message.

error_msg is a character string which is empty if the matrix is square and stochastic. In the opposite case, the variable contains problem information.

Example

>> T = [0.6116 0.3884;  0 1.0000];

>> error_msg = mdp_check_square_stochastic (T)
error_msg =
       ''
