function x = ss_dtmf(number,dt,nd,np)
nl = length(number);

tp = 0:1:np;
xp = zeros(1,length(tp));
for i=1:nl
xi = ss_dtmf1(number(i),t);
x = [x,xi];
x = [x,xp];

The line
Function for DTMF:
is not a valid executable line. You need to comment it out.

Try commenting out your comments so that you can run your code.
Functions must be called, so I'm asking how you are calling your function ss_dtmf? Specifically what are your input values for number, dt, nd, and np?
What error messages are you getting? Please copy and share all the red text.

function x = ss_dtmf(number,dt,nd,np)
x=[];
for i=1:length(number)
x = [x,ss_dtmf1(number(i),0:nd:dt),ss_dtmf1(12,0:np:dt)];
end
end
function x = ss_dtmf1(n,t)
f=[941,697,697,697,770,770,770,852,852,852,941,941,0;1336,1209,1336,1477,1209,1336,1477,1209,1336,1477,1209,1477,0];
x=sin(2*pi*f(1,n+1)*t)+sin(2*pi*f(2,n+1)*t);
end

This should do exactly what you want.
function x = ss_dtmf(number,dt,nd,np)
x=[];
lt=linspace(0,dt,nd);
lp=linspace(0,dt,np);
for i=1:length(number)
x = [x,ss_dtmf1(number(i),lt),ss_dtmf1(12,lp)];
end
plot(x);
end
function x = ss_dtmf1(n,t)
f=[941,697,697,697,770,770,770,852,852,852,941,941,0;1336,1209,1336,1477,1209,1336,...
1477,1209,1336,1477,1209,1477,0];
x=sin(2*pi*f(1,n+1)*t)+sin(2*pi*f(2,n+1)*t);
end
for example:
x=ss_dtmf([2 0 8 7 3 9 6 1 0 3],.1,1000,50);
