# Really simple problem...... IF function????

## Really simple problem...... IF function????

(OP)
I cannot believe that there isn't a block for an IF command or a high value wins block. All I want to do is only allow the highest value to pass through to the output i.e.

Input x and y. IF x>y then output is x but if y>x then the output is y.

I have been through the library and can't find anything but surely you must be able to do this using a Simulink block...

Hope someone can help...

Why can't you used the MinMax math operator?

### RE: Really simple problem...... IF function????

Perhaps you can add a block with Matlab script/function to implement it.

### RE: Really simple problem...... IF function????

You can use the relational operator from the math operations library. there you have two inputs that you can compare.
For example if your inputs are x and y and you choose >= the block will compare x and y. If x>=y the output will be 1 if x<y the output will be 0.
I hope this helps.
Bye.
