I would like to get something like this in Matlab:
x = round(rand*10);
switch (x)
case {0:10}
disp('x between 0 and 10');
case {11:20}
disp('x between 11 and 20');
case {21:100}
disp('x between 21 and 100');
end
But unfortunately it doesn't work. Don't enter in any of the cases. Do you know how can I do that?
A little simple than Luis Mendo's Answer, just use num2cell to convert your matrix of doubles into a cell array of doubles.
x = randi(100);
switch (x)
case num2cell(0:10)
disp('x between 0 and 10');
case num2cell(11:20)
disp('x between 11 and 20');
case num2cell(21:100)
disp('x between 21 and 100');
end
num2cell automatically picks entries one by oneThe problem is that {0:10} is not {0,1,...,10}, but rather {[0,1,...,10]}. So it's a single cell containing a vector, and of course x never equals that vector.
To solve it, use cell arrays with one element per cell. To create them from vectors you can use mat2cell (or better yet num2cell, as in @thewaywewalk's answer)
x = round(rand*10);
switch (x)
case mat2cell(0:10,1,ones(1,11))
disp('x between 0 and 10');
case mat2cell(11:20,1,ones(1,11))
disp('x between 11 and 20');
case mat2cell(21:100,1,ones(1,81))
disp('x between 21 and 100');
end
Or, more easily, use elseifs instead of switch, and then you can use vectors and any:
x = round(rand*10);
if any(x==0:10)
disp('x between 0 and 10');
elseif any(x==11:20)
disp('x between 11 and 20');
elseif any(x==21:80)
disp('x between 21 and 100');
end
Much cleaner solution is to set switch to true. I use this approach all the time given that the "switch" construction is easier to read than the "if then else" construction.
For example:
i = randi(100);
switch true
case any(i==1:50)
statement
case any(i==51:100)
statement
end
