I'am not sure to totally understand your question, but if you want to update a parameter in a structure, you have to pass the structure to update as argument of your function.

Moreover, if prop is the parameter, you should use an dynamic allocation using a string in your function :

function [ s_struct ] = set_s( s_struct, number, prop, value )
    s_struct(number).(prop) = value;
end

Using it this way :

s_vec = set_s(s_vec, 2, 'Hello', 5);

It will update the second value to the parameter 'Hello' to 5.
