# Find Maximum one of numerical arguments

Asked by Light on 27 May 2013

How can i find max of 30 arguments max(H1,H2.....H30)

But error message occured "Error using max Too many input arguments.MAX with two matrices to compare and a working dimension is not supported"

Is there any other way?

Put brackets around them to make them a single array, as my answer below shows.

Try this:

```[maxValue, indexAtMaxValue] = max([H1, H2, H3, H4, ...ETC...... , H29, H30]);
```

[maxValue, indexAtMaxValue]=max([H01,H12,H23,H14,H45,H56,H47,H77,H78,H89,H910,H811,H1112,H1113,H1314,H1315,H1516,H1617,H1618,H1819,H1520,H2021,H2022,H2223,H2224,H2425,H2426,H2627,H2628,H2829]);

Result:

maxValue =

`     0`

indexAtMaxValue =

`     1`

H values less than 0.01.... What will i do

Once again: You forgot to give us the values for the H's, so we can't try my answer.

To drive the point home: How on earth am I supposed to know what value H01 takes on? Or what value any of the other variables have? The answer is I don't. Unless you supply them to me. GIVE ME CODE THAT SAYS:

```H01 = 0.003342243423;  % or whatever.
...
H2022 = 0.233423423423; % or whatever.
and so on, for all the H's.
```

So sorry!! My CODE is almost 500 rows and all of it relative and it is changed in next iterations .......

Anyway!!! Thanks for your big help :-))))
