how do i save the contentes of a function with out save?

im doing a project and i have a menu were the button 5 is to save the contents of a function in a new file

-escreve(mtx, assigment, cost);        % this is the previous button that grabs a matrix and 2 variables

this is our function 'escreve':

function [] = escreve(matriz, assignment, custo)
fprintf('Custo total --> %.2f', custo);
[desprez, numeroTrabalhadores] = size(matriz);
trinca = length(assignment);
 for a = 1: numeroTrabalhadores
                custo=matriz(a,assignment(a));
                fprintf('\ntrabalhador %d---> tarefa %d (custo %.2f)',a,assignment(a),custo);
 end
end

that gives this :

Custo total --> 33.00
trabalhador 1---> tarefa 5 (custo 3.00)
trabalhador 2---> tarefa 3 (custo 3.00)
trabalhador 3---> tarefa 1 (custo 1.00)
trabalhador 4---> tarefa 4 (custo 23.00)
trabalhador 5---> tarefa 2 (custo 3.00)

i wana save what the function gives as a new file but i cannot use save and load

thanks in advance

the sugestion our prof gives is to use fopen fprintf and fclose

Read about dlmwrite() it will help you solve your homework

[vicente simas]

he says we can not use dlms

[Walter Roberson]

Is there a reason not to use the functions the professor suggested ?

[vicente simas]

we can not use the load and save function and dlm as well because either are not in the book or are restricted for this project so the hint was to use fopen the fprintf and then fclose

escreve(mtx, assigment, cost);        % assuming the input arguments are already defined


function escreve(matriz, assignment, custo)
fprintf('Custo total --> %.2f', custo);
[desprez, numeroTrabalhadores] = size(matriz);
trinca = length(assignment);
fileID = fopen('sample.txt','w');
 for a = 1: numeroTrabalhadores
                custo=matriz(a,assignment(a));
                fprintf(fileID,'\ntrabalhador %d---> tarefa %d (custo %.2f)',a,assignment(a),custo);
 end
 fclose(fileID)
end
