How to call a function in an m file in a function in another m file in MATLAB

Hi,

I have two functions in separate m files in the same directory given as:

1st function:

function [P] = Calculate_Transmission_Prob_Matrix()
% this function calculates a transmission probability matrix (i.e., P)

2nd function:

% this function calculates stationary_probability by combining the transmission probability matrix (P) and a matrix of ones which is of the same size as P.

function stationary_probability = Calculate_Stationary_Probability()

Here's how i called the 1st function in the second function:

      [P] = Calculate_Transmission_Prob_Matrix();

      stationary_probability_initialize = ones(size(P)); 
      stationary_probability = [stationary_probability_initialize P];

Is this correct? If not how can i correct it?

Looks correct, other than you don't need the enclosing brackets in [P] in either the function definition or when you call it. You only need them when there are more than 1 return variables. Also, stationary_probability_initialize and P must have the same number of rows for you to stitch them together side by side, but your ones() function will handle that fine.
