How to find in cell structures?

I have the following cell structure:

1x30 double
1x23 double
1x23 double
1x23 double
1x23 double
1x23 double
1x23 double
1x25 double
1x35 double

I want to find whether a number is present in one of these and want to know the index of that. So for instance the number 5 is present in double 1, 5 and 7, so the output should be [1 5 7]. Can this be done?

Take a look to cellfun

Unclear, attach your data as .mat file.

Read about ismember, find.

Off the top of my head, something like this may work:

find( cellfun( @(x) any( find( x == 5 ) ), myCell, 'UniformOutput', false ) )

where myCell is your cell array.

At least it may give you ideas to get to the right solution, though I'm sure someone else will quickly come along with a correct or better solution if this is not it!

Answer 1

[madhan ravi]

v=cellfun(@(x) any( x == 5 ), yourcell);
Wanted = find(v) % Adam was almost right , but a minute tweak

Simpler:

find(cellfun(@(x)any(x(:)==5),yourcell))

That any(find(...)) syntax is rather obfuscated, and should be avoided.
