MATLAB: Copy element of matrix to another matrix

matrixprogramming

hello all,,
i wanna ask about how to copy element of matrix to another matrix
example :
i've matrix B and i want the element of matrix B copied into another matrix(matrix F)
this's my code
a= input ('Input Number of Data :');
for c=1:a
int2 = ['Input The First Score - ',num2str(c),' :'];
int3 = ['Input The Second Score - ',num2str(c),' :'];
str = ['Input Category ke - ',num2str(c),' :'];
b(c,1) = input(int2);
b(c,2) = input(int3);
f{c,3} = input(str,'s');
end;
everytime i use command "f=b(:,1:2)" the element of matrix f is missing and that's change with element of matrix b
i want the element of matrix f still in matrix f although the element of matrix b copied into matrix f
please help me
NB : sorry for my bad english 🙂

Best Answer

If you want to copy for each c the first two elemens of b to f, use inside the for loop
f(c, 1:2) = b(c, 1:2);
Or you can also do this for all rows outside the for loop using
f(:, 1:2) = b(:, 1:2);
