checking an interval by using switch case function

5 views (last 30 days)
Hello everyone,
I'm trying to find the range of a number by using the switch-case function. How can I find this number? In other words, let's say we have three intervals, 10-50, 50-70, 70-100. If our input is 15, how can I insert it into the first case by using switch case function?

switch and case are not the best tools for this application, at least not alone. If you have a small number of potential cases either use if and elseif or use discretize to bin the continuous values into discrete bin numbers and then use switch and case on those discrete bin numbers.
x = randi([10 100], 1, 5)
x = 1×5
22 40 65 79 73
d = discretize(x, [10 50 70 100])
d = 1×5
1 1 2 3 3
