Thread Subject: Subscript indices are real integers but getting error saying they are not?

Hi,

I have been scratching my head about this one and a look through the other posts hasn't helped so I thought someone might be able to help. I have an m-file in which I form a 4-d double array (11x11x12x26) of sea surface temps (sst) and I want to get the means along the 3rd dimension, so I have a line

avg_sst = mean(month_array,3)

which gave the error:

"Subscript indices must either be real positive integers or logicals"

so I tried using for loops and reshaping the array, etc but always got the same error.

Can anyone help?

Thanks,

Colm

one of the (likely) solutions

     x=1:5;
     clear mean;
     mean(x)

I'm sorry. I don't understand what you mean.

He means that likely you have a variable named 'mean' that that
that is interfering with your use of the function named 'mean'.

That was it. Thanks for your help. (I feel like an idiot for not picking that one up!)
