is there any command to find a maximum value of a matrix containing negative numbers also ??

x =

    -1    -1    -1    -1     0    -1    23    19

i need to find a maximum value for this. can i get a single line command ??

Answer 1

[Iain]

No single line command, but

 largest_val = (-min(x) < max(x))*(max(x)-min(x))+min(x);

is cheeky and it preserves the sign.

Answer 2

You need the "maximum value". Then there is no reason for ABS, but you can call simply:

result = max(x)

Answer 3

[Andreas Goser]

Not sure if

max(abs())

counts as single command for you...

[Manikanta Prasanth]

thank you Mr. Andreas for the reply. But, i should not use abs in my case. Is there any alternative ??

[Andreas Goser]

"I should not" because of a good technical reason or just because someone told you / this is part of a homework? I can think of sorting the values first and then take the largest of the (1) and (end) values.

What about

sqrt(max(x(:).^2))
