How to take a value between two values

hello, please help me.
i couldn't use "if" statement to take 'r' value. The 'r' value depends on 'd' value. but i don't know how to make the code for this.
lets take an example. when i input 'd' value as 15, the 'r' value that i got is 1.6 instead of 1.8. what should i do?

make small changes in the if statement. The code given below is the right way to use if.
if (10.2 <= d) && (d < 13)
r = 1.6
elseif (13.5 <= d) && (d < 20.0)
r = 1.8
elseif (20.0 <= d) && (d < 22.4)
r = 2.0
end

If you hover over the underlined <= operators in the code in the MATLAB Editor, you will see a Code Analyzer message explaining why that code doesn't do what you think it does and suggest how you can modify the code to do what you likely want to do.
Alternately, you could use the discretize function to discretize your data without a (potentially lengthy) if / elseif / elseif / elseif ... / end statement.

@Stephen23 like this -
d = randi([5 25],1,8)
X = [10.2,13,13.5,20,22.4];
Y = [1.6,1.8,2,Inf];
out = discretize(d,X,Y)

d = [11,15,21];
X = [10.2,13.5,20,22.4];
Y = [1.6,1.8,2,Inf];
Z = interp1(X,Y,d, 'previous')
