Hi everybody!
I have a column in a csv file with 0 and 1 and I want to replace all the 0 values by FALSE and all the 1 values by TRUE. Anybody knows how can I do that? Thanks in advance!
I have been trying to do this but it doesn't work.
s(s==0)='FALSE'

s(s==0)='text';
won't work because you're trying to change datatypes piecewise in an array.
SOTOO,
>> s=rand(10,1)>0.5;
>> v={'t';'f'};t=v(s+1)
t =
't'
'f'
't'
't'
'f'
'f'
'f'
't'
'f'
't'

Oh. OK. Thought I’d been behind the door again.
Know about ‘table’ but haven’t used it much yet.
