How can i get the largest value among three variables?

a=100;
b=50;
c=200;

The largest is c, then it will set "max=c"


Can anyone show me how to do it?

arr = [a,b,c];
arr_name = {'a','b','c'};

[maximum,ind] = max(arr);

str = ['max = ',arr_name{ind}];
disp(str)

% the max value is stored in the variable name 'maximum'

Hi, did you read 

>>doc max

Just put those values in a vector and use max()

In article <ho8fll$t82$1@fred.mathworks.com>, impengswee@gmail.com

Place a, b, c in one array and check out the function "max".

Vector=[a;b;c];
max=max(Vector);

thank you.

Really BAD practice.
Don't use matlab builtin functions as variable names.

To see what I'm talking about try this:
max=max([1 10])
max([20 30 100])

I second Oleg's message about variable names.  Also, here is another approach for your problem.


mx = max(a,max(b,c))  % The largest value of scalars a,b,c.
