How to make a ramp function that start in point a and finish in point b. [a,b]. And with value 0 outside the interval

I want to build a ramp function that start from point a

and finish in point b. [a,b]

I have constructed a code of a ramp functon that starts from 0 and finish in point b.[0,b].

this is the code:

 hold on
    b =2  % time in wich the ramp finish
    a=1  %time in which the ramp start
    t = [0:0.01:15]';  %timespan of the ramp function
    for impAmp = [3 5 10] . %height of the ramp 
    function
    rampOn = @(t) t<=b;
    ramp =@(t) t.*impAmp.*rampOn(t);
    plot(t,ramp(t))
    end

But I want to define a new code of the ramp function defined in the interval [a,b]. And a value of 0 outside the interval.

I have tried this code. But it modified all the ramp function.

 hold on
    b =2 % time in wich the ramp finish
    a=1 %time in which the ramp start
    t = [0:0.01:15]';%timespan of the ramp function
    for impAmp = [3 5 10]%height of the ramp function
    rampOn = @(t) a<t<=b;
    ramp =@(t) t.*impAmp.*rampOn(t);
    plot(t,ramp(t))
    end

Hi

A small modification in the code you defined for the interval [a,b].

Using this line would yield you the expected result.

rampOn = @(t) t>=a & t<=b;
