19 lip 2021 · How can i plot a unit step function or a piecewise function in Matlab? ie: h (t)=u(t-2)-u (t-4)? or another example: h (t)= {0 for t<0, 1 for 2<t<3, 0 for t>3. Also, how can i plot a periodic square wave with thresholds in matlab? 2 Comments. the cyclist on 22 Aug 2019. This sounds like homework.
Here are some statements that generate a unit impulse, a unit step, a unit ramp, and a unit parabola. t = (-1:0.01:1)'; impulse = t==0; unitstep = t>=0; ramp = t.*unitstep; quad = t.^2.*unitstep; All of these sequences are column vectors that inherit their shapes from t .
18 lut 2023 · Unit Step Sequence. A unit step sequence is denoted as u(n) and is defined as. Sinusoidal Sequence. A sinusoidal sequence is formed with the help sine or cosine function and it is denoted by x(n)=A cos(ωo. n +ϕ) where ωo is the frequency (in radian per sample) and ϕ is the phase (in radians). Exponential Sequence
This MATLAB function evaluates the Heaviside step function (also known as the unit step function) at x; the Heaviside step function returns 0 for x < 0, 1/2 for x = 0, and 1 for x > 0.
17 lip 2024 · plot (t,unitstep,'b','linewidth',3) % Repeat, with everything shifted to the right by 1 unit: unitstep2 = zeros (size (t)); unitstep2 (t>=2) = 1; hold on. plot (t,unitstep2,'r:','linewidth',2) box off. https://www.mathworks.com/matlabcentral/answers/323383-plotting-a-unit-step-function-without-heaviside#comment_426319.
In the following example, we use MATLAB to construct the Laplace transform of a step response, plot the response with the impulse command, and compare the result with a plot obtained using the step command. We also illustrate the use of the initial- and final-value theorems.
In this video we are looking at the unit step function and what different operations can be performed using it such as scaling, translation etc in Matlab.
