std in matlab cell

 i have cell for exaple {1x7 cell} in cell Z{1} ans = 

Columns 1 through 6

    [1x3 double]    [1x3 double]    [1x3 double]    [1x3 double]    [1x3 double]    [1x3 double]

Column 7

    [1x3 double]

>> Z{1}{1}

ans =

    5.4000    8.3000   15.8000

I want the standard deviation of each element in the array

for example: std(5.4), std(8,3) std(15,8)

I dont know how to use standard devation in cell array.

Thanks.

What are you expecting with std(4.5) ?

Maybe you mean the std of each array in your cell array Z

i know std(4.5)=0 , but i have std each element in matrix,

Answer 1

[Azzi Abdelmalek]

Z={[1 2 3],[6 8 12],[3 12 20]}
out=cellfun(@std,Z)

The result will be a 1x3 array

std of [1 2 3]
std of [6 8 12]
std of [3 12 20]

Thanks, I'll use it
