Dear experts.

I am not a MATLAB user myself but a portion of my work requires me to plot figures on MATLAB. I am unable to figure this out and google was not any help. I would be grateful if somebody gives me a clue about how to plot this figure? I would like to use this figure as my starting point to carry on my practice.

I wish you a good day

Here is patch use

x = 0:0.1:1;
y = sqrt(x);
cla
patch([0 0 0],[0 1 0],[0 0 1],'b')      % vertical triangle
patch([1 0 x],[1 1 y],[0 0 x*0],'b')    % horizontal triangle
patch([1 0 x],[1 1 y],[0 0 1-y],'b')    % diagonal triangle
% use for loop to create cylindrical part
for i = 1:length(x)-1
    dx = x(i:i+1);
    dy = y(i:i+1);
    patch([dx flip(dx)],[dy flip(dy)],[1-dy 0 0],'b')
end
