How can I convert a vector to a cell array?

问题:

I have a column vector I want to convert to a cell array such as:

A = rand(10,1);

B = cell(10,1);
for i=1:10
    B{i} = A(i);
end

B = 
    [0.6221]
    [0.3510]
    [0.5132]
    [0.4018]
    [0.0760]
    [0.2399]
    [0.1233]
    [0.1839]
    [0.2400]
    [0.4173]

How can I do this without an explicit for loop? I tried:

B{:} = A(:)

and

[B{:}] = deal(A)

with no luck...

Also if possible, how can I do the same thing for a matrix, i.e. have each element in a cell by itself?

回答1:

Use the function num2cell:

B = num2cell(A);

Works with matrices too.
