That’s the same way I iterated above. It’s a bit clunky getting the contents of the scalar cell, but it is the way to iterate on a cell array.

–Loren

>> for a = {’b', ‘c’}; a, end;
a = ‘b’
a = ‘c’

But actually

>> whos a
Name Size Bytes Class Attributes
a 1×1 62 cell

is not a string - one needs to

>> for a = {’b', ‘c’}; a=a{1}, end;

which I find inpractical + ugly. Am I missing something/is there a better way to iterate through strings list?

thanks,

The foreach-functionality is included in Matlab’s FOR - isn’t it?. More often than not, my for-loops are through cell and structured arrays. The arrays may hold anything even funtionhandles of nested functions. Are cell arrays less powerful than collections?

It took me some time to appreiciate the full power of the for-loops in Matlab.

- per

Depending on the collection, there’s cellfun, arrayfun, and structfun. And yes, you can use A(:).’ to make a single row. Or you can use reshape(A,1,[]).

I’m glad the editor warning on loop variables is helpful to you.

I have settled for a variant of solution 2. I’d use ” for str = fn(:)’ “. The column operator is to make sure I get to a row regardless if ” fn ” is row or column. (ie context independent - maybe there is a single “make row” operator instead of ” (:)’ ” ?)

**Unneeded indices are bad. Not needing them for anything else but to get to the value, one tends to choose the obvious i,j,k without sufficient attention so may well overwrite the same named loop vars in an outer loop. The editor warns so is of great help here.

I don’t see how you can do it simply for your set up since you have both cells and numeric arrays and the same functions don’t operate on both and structfun wants one function (though I guess it could be a complicated one). Besides, for non-uniform output, structfun outputs a struct so I can’t see how you’re better off.

I think num2cell is what you need to spread your numeric array out into a cell. Try this:

s.a={'first', 'second'};
s.b=[1.1 1.2];
s.c=[30.1 33.2];

mycell= [s.a ; num2cell(s.b); num2cell(s.c)]'

mycell =
    'first'     [1.1000]    [30.1000]
    'second'    [1.2000]    [33.2000]

Your questions do not have simple answers and are simply too general to give you good answers. They depend very much on circumstances. Vectorization sometimes helps a lot, and sometimes not. The amount of savings depends on all the details. You can call a function and return a vector of structures. See the documentation. Input vectors don’t have to be the same size for all functions, but it depends what function(s) you are referring to.
