Can I assign a single value to multiple elements of a cell array without a loop

For example, I have an array that looks like

myArray = 
    [3]    []    [3]    []

I'd like to fill out the empty elements of myArray with zeros, but, obviously, the following doesn't work:

myArray{find(cellfun(@isempty,myArray))} = 0

Obviously, I could write a loop, but there has to be a better way!

Thanks for any suggestions!

Answer 1

You almost had the syntax right:

myArray(find(cellfun(@isempty,myArray))) = {0}

Or you can just use logical indexing and skip the find:

myArray(cellfun(@isempty,myArray)) = {0}

[Stephen23]

The find is completely superfluous and just slows the code down, so use the second version (uses logical indexing ). A slightly faster alternative is to use the overloaded isempty option:

myArray(cellfun('isempty',myArray)) = {0}

Your main problem is the confusion between () and {}. Secondly, use logical indexing, rather than find:

myArray(cellfun(@isempty, myArray)) = {0};
