MATLAB: How can you obtain a system time response to a ramp function in Matlab

ramp function

I need to explain this in words and as I am new to matlab I do not know how to obtain a ramp function from a system time response via Matlab.

There's a solution by Azzi Abdelmalek here

t=0:0.1:10
alpha=2
ramp=alpha*t         % Your input signal
model=tf(1,[1 20 3]);    % Your transfer function
[y,t]=lsim(model,ramp,t)
plot(t,y)

MATLAB: Am I finding the Step and Impulse Response Correctly

t=0:0.1:10
step([1],[1,3],t);

%or

y=step([1],[1,3],t);
plot(y)

%and

impulse([1],[1,3],t);

%or

y=impulse([1],[1,3],t);
plot(y)

%or

N=1;
D=[1 3];
model=tf(N,D)
step(model)
figure
impulse(model)

%if x(t) is any input signal use

t=0:0.1:10;
x=exp(-t)
lsim(model,x,t)

MATLAB: Constant Ramp

The block does exist in R2010b as well and was part of the Signal Processing Blockset (which has since been repackaged into the DSP System Toolbox). Perhaps you don't have Signal Processing Blockset installed in your R2010b version?
