Is there a way to use the switch construct by checking with operators like > and < and not doing an equality check?
for example :
x = 12;
switch x
case x < 3
% statementents
case x >= 3 && x < 10
% statements
case x >= 10 && x < 20
% statements
otherwise
% statements
end
Why does it always execute the statements in the otherwise section? What's wrong?

A switch statement executes the first case that is true. Try this instead.
x = 12;
switch true
case x < 3
% statementents
case x >= 3 && x < 10
% statements
case x >= 10 && x < 20
% statements
otherwise
% statements
end

Ran in:
Or discretize your data and then switch on the bin into which your data falls.
x = 12;
whichBin = discretize(x, [-Inf 3 10 20 Inf])
whichBin = 3
x = 42;
whichBin = discretize(x, [-Inf 3 10 20 Inf])
whichBin = 4
