Way to set a cell array of strings to 0 or 1 depending on the string?

I have a cell array of strings (1000x1 cell) containing either "On" or "Off". Is there a simple command to replace "On" by 1 and "Off" by 0 in the whole array? I would like to avoid using a FOR loop. Thanks!

One way:

c = {'On','Off','On'};
tf = strcmp(c,{'On'})

One way:

c = {'On','Off','On'}
tf = ismember(c,{'On'})

Then do

x = double(tf)

if you really need numeric, rather than the logical array tf.
