Map function in MATLAB?

Question

I\'m a little surprised that MATLAB doesn\'t have a Map function, so I hacked one together myself since it\'s something I can\'t live without. Is there a better version out

Answer 1

In addition to vector and element-wise operations, there's also cellfun for mapping functions over cell arrays. For example:

cellfun(@upper, {'a', 'b', 'c'}, 'UniformOutput',false)
ans = 
    'A'    'B'    'C'

If 'UniformOutput' is true (or not provided), it will attempt to concatenate the results according to the dimensions of the cell array, so

cellfun(@upper, {'a', 'b', 'c'})
ans =
ABC
