I want a code to which if I give x, it provides me with value of y and y should be as given in above photo.
My attept:
clear; clc;
xp = 100;
x1 = 50;
dx = 0.2;
depth = 1;
all_x = -xp:dx:xp;
y1 = linspace(0,0,length( [-xp:dx:-x1] ) )
y2 = ???
y3 = linspace(0,0,length( [x1:dx:xp] ) )
all_y = [y1 y2 y3];
I am unable to write a relation for y2

>> xp=5;
>> x1=1.5;
>> depth=2.3;
>> Xv = -xp:0.1:xp;
>> Yv = min(0,depth*abs(Xv)/x1 - depth);
>> plot(Xv,Yv,'-*')
