Hi, I have four symbolic functions, say y_caseA, y_caseB, y_caseC, and y_caseD, and I want the region that satisfies
ineq = (Y > y_caseA) & (Y < y_caseB) & (Y<y_caseC) & (Y>y_caseD);
Can someone please help with this. Thank you

Ran in:
syms Y
y_caseA = 5;
y_caseB = 10;
y_caseC = 7;
y_caseD = 3;
ineq = piecewise((Y > y_caseA) & (Y < y_caseB) & (Y<y_caseC) & (Y>y_caseD),1,0)
ineq = 
fplot(ineq, [0 15])
ylim([-.1 1.1])
