I want to create the attached waveform using simple basic matlab code. Can someone please help me through the process on how to generate such waveforms through matlab coding not using any matlab defined function. Appreciate all the help. 댓글을 달려면 로그인하십시오.

The given waveform is a piecewise smooth function, and it can be constructed as follows:
t = 0:0.1:2000;
% Defining the Segments
x1 = 0.07*(t < 200); % segment 1
x2 = ((0.37 - 0.07)/( 600 - 200)*t - 0.08).*(( 200 <= t) & (t < 600)); % segment 2
x3 = 0.37*((600 <= t) & (t < 800)); % segment 3
x4 = ((0.70 - 0.37)/(1200 - 800)*t - 0.29).*(( 800 <= t) & (t < 1200)); % segment 4
x5 = 0.70*((1200 <= t) & (t < 1800)); % segment 5
x6 = ((0.00 - 0.70)/(2000 - 1800)*t + 7.00).*((1800 <= t) & (t < 2000)); % segment 6
% Combining all segments and plotting it
x = x1 + x2 + x3 + x4 + x5 + x6;
plot(t, x, 'linewidth', 1.5)
ylim([0 1]), grid on, xlabel('t'), ylabel('x(t)'), title('Piecewise Smooth Function') ##### 댓글 수: 1표시숨기기 없음
