To modify s, use s subss,old,new if old and new are both vectors or cell arrays of the same size, subs replaces each element of old with the corresponding element of new if old is a scalar, and new is a vector or matrix, then subss,old,new replaces all instances of old in s with new, performing all operations elementwise. If old and new are both vectors or cell arrays of the same size, subs replaces each element of old with the corresponding element of new. You can generate matlab functions, simulink function block, and simscape. Graficando con matlab an engineer to change the world.
