Here is a simple Matlab function that will let you save a matrix in a text file using start and end text delimiters: 1 function append_value (file, name, value ) 2 dlmwrite ( file, , 'delimiter', '', '-append' ) 3 dlmwrite ( file, value, 'delimiter', '\t', 'precision', 16, '-append' ) 4 dlmwrite ( file, , 'delimiter', '', '-append' ) 5 endĪn example of using the above function to save a few matrices in a text file: 1 A = rand ( 4, 5 ) 2 % Save A to "matlab_data_v2.txt" between the delimiters "Start_A". load() function from Armadillo to get the data as a matrix in memory. The idea is to use some kind of delimiters between two records, read the content of the first record (matrix) in a C++ stringstream after which you can use the. This last approach can be generalized for the case when you need to transfer more than one matrix from Matlab. load() function from Armadillo also works with C++ streams, e.g.: 1 std :: ifstream file ( "matlab_data.txt" ) 2 3 arma :: Mat A 4 A. Using a separate text file for every one of them is not only tedious and error prone, it is also a relatively slow process. Imagine that you need to move many small matrices of various dimensions. The above procedure works well if you need to transfer one or two matrices from Matlab to Armadillo, but it doesn’t scale. Reading the matrix from matlab_data.txt in Armadillo can be done with: 1 arma :: Mat A 2 A.

For example, the next Matlab code will generate some data and save it in a text file that can be loaded from Armadillo: 1 A = rand ( 4, 5 ) 2 3 % Save the matrix A to "matlab_data.txt" the content of the file is overwritten 4 dlmwrite ( 'matlab_data.txt', A, 'delimiter', '\t', 'precision', 16 )
