please explain this error

I'm using matlab 2012a.

When I tried the following command it gave me an error.

Can you please explain it to me?

Thanks

Command:

max(-3/2, 7, 1.4)

Error using max
MAX with two matrices to compare and a working dimension is not supported.

dav, I believe what you are trying to do is the following

 max([-3/2, 7, 1.4])

The values you want to find the maximum of need to be arranged in arrary form, that's why the square brackets.

yep, I figured it out after a while. :) Thank you very much!

Answer 2

[Deeptanu Datta]

I tried running the code

clc;

clear all;

close all;

x1 = [2 3 6 9 7 4 1 5 9 36 47 25 ];

[~, x3] = max(x1,[])

It gives an error "MAX with two matrices to compare and two output arguments is not supported"

But, when I write [~, x3] = max(x1,[],2) or [~, x3] = max(x1), it works.

Please explain
