Hello, I have vector (ind), used in a while loop and whose length is changing in every loop. I need to save (in a table or a mtrix-if it's possible)the value of this vector in each iteration and ofcourse before it change. Thanks you,

在 MATLAB Online 中打开

Use a cell V to store the vectors

for i = 1:N
     vec_of_variable_length = ...
     V{i} = vec_of_variable_length; 
end

You cannot store vectors of different length in a matrix, because matrices are rectangular by definition. Using a cell vector as in Thorsten's example is sufficient.
