Ran in:
arr = ['some'; 'thee'; 'time'; 'hour']
arr = 4x4 char array
'some' 'thee' 'time' 'hour'
mat = double(arr)
mat = 4×4
115 111 109 101 116 104 101 101 116 105 109 101 104 111 117 114

The original version had 'the' instead of 'thee' so it could not be represented as a character array... which is why David answered with {}

arr={'some'; 'the'; 'time'; 'hour'};%must be cell array since lengths are not the same
for k=1:length(arr)
arr{k}=double(arr{k});%simple for-loop converts
end

is there way to convert it without for loop?

No. The best you can do is hide the loop
output = cellfun(@double, arr, 'uniform', 0)
