I am trying to make a for loop that put symbolic expressions inside a matrix ( in positions given by index of for loop) and i get this error:
??? The following error occurred converting from sym to double:
Error using ==> mupadmex
Error in MuPAD command: DOUBLE cannot convert the input expression into a double array.
If the input expression contains a symbolic variable, use the VPA function instead.
Can you help me ?
Thanks in advance,

Do not initialize the matrix to zeros(): that requires numeric values instead of symbolic.
Try
matriz_N = sym(zeros(3, 6+4*k));
